  • TAT (48-59) amide


    Biotin-Tat (47-57) is a cell penetrating cationic peptide derived from the N-terminus of the Tat protein, which is a trans-activator of the transcription protein present in the human immunodeficiency virus (HIV). Specifically Biotin-TAT (47-57) is located within the arginine-rich basic domain 48-60 of the TAT peptide which as a whole has three domains which function to aid HIV through transactivation, DNA binding and nuclear transport. As a cell penetrating peptide (CPP) TAT aids in the cellular uptake of molecules and hence serves a valuable purpose in transduction methods. This property has been demonstrated through its ability of allowing toxins such as the neurotoxin Botulinum neurotoxin Type A, produced by the Clostridium botulinum type A bacteria to penetrate the skin barrier non-invasively.This peptide has an uncharged C-terminal amide.

  • IFNB1 (118-132) Human deimmunised


    Recombinant human interferon-β (IFNB) is a therapeutic for specific stages of multiple sclerosis (MS). However, a significant portion of patients develop neutralising antibodies within two years which prevent the clinical efficacy of the treatment- this was correlated to a specific rise in IgG. Sequencing of IFNB1 revealed CD4+ T cell epitope residues (118-132) that contain critical T cell activation residues. Identifying these sequences allows them to be manipulated to provide new interferon treatments that reduce the capacity to induce neutralising antibodies in MS patients. In addition, the critical residue isoleucine has been mutated to valine and shown to reduce the immunological response to this epitope. This IFNB1 (118-132) epitope can be used for immunological investigations as a deimmunised version of the epitope. In addition, it can be used as a control for T cell activation and antibody recognition via immunoassays and immunohistochemistry. This may provide further insights into specific haplotypes correlating to IFNB responses in MS treatment.

  • PAR-2 Agonist amide


    Thrombin receptor inhibitory peptide (TRIP). Thrombin activates members of the PAR family of receptors to initiate a variety of signalling pathways.Protease activated receptors (PARs) are a distinctive four-member family of seven transmembrane G protein-coupled receptors (GPCRs) widely expressed in inflammatory cells. PARs are cleaved by certain serine proteases to expose a tethered ligand domain, this ligand domain then binds to and activates the receptors to initiate multiple signalling cascades. This peptide mimics the tethered peptide ligand of PAR- 2, but lacks the S42 residue which is important for receptor activation, and therefore acts as a thrombin antagonist peptide.

  • PA protein (Influenza A virus)


    The PA protein is a subunit of the influenza virus polymerase complex and its endonuclease activity is vital in viral genome replication. As a phosphoprotein it is a casein kinase substrate and its N-terminus is responsible for the activation of a proteolytic process in which co-expressed proteins are degraded.During viral RNA synthesis PA produces 5' capped RNA oligonucleotides due to it cleaving the 5' terminus on pre-mRNA. It is possible that the PA protein could be used as a target in antiviral chemotherapy.

  • Biotin Apolipoprotein A-I (APOA1)(86-101)


    Apolipoprotein A-I enables the efflux of fat molecules from within cells as high-density lipoprotein (HDL) particles for transport back into LDL particles or to the liver for excretion. HDLs are one of five major groups of lipoproteins. Increasing concentrations of HDL particles are strongly associated with decreasing accumulation of atherosclerosis within the walls of arteries. Apolipoprotein A-I is often used as a biomarker for prediction of cardiovascular diseases, such that low levels of APOA1 are associated with an increased risk of adverse events in patients with coronary artery disease. In such cases, APOA1 can be used as a biomarker to predict cardiovascular disease progression.This peptide contains a covalently bonded N-terminal Biotin tag that can be used for detection and purification.

  • Amylin (1-37) Human


    Amylin, also known as islet amyloid polypeptide (IAPP), is a peptide hormone which is deficient in patients with diabetes mellitus (DM). Amylin is co-secreted with insulin from the pancreatic β-cells. It inhibits glucagon secretion, delays gastric emptying, and thus acts as a satiety agent.  Amylin peptide is capable of forming aggregates, and pancreatic amyloid plaques are present in 90% of patients with DM. Formation of these plaques may be inhibited by insulin via the formation of heteromolecular complexes. Amylin is also involved in adiposity signalling and body weight regulation.Amylin is expressed in the human placenta during pregnancy where it may help regulate food intake by both the mother and foetus, and is involved in foetal development of bone, kidneys and pancreas.

  • AF10847


    Activation of the inflammatory response is critical to various infectious agents. Pro-inflammatory cytokines like-IL-1α and IL-1β are upregulated upon the initial detection of infection and bind to IL-1R1 to activate the signalling cascade. However, a hyperinflammatory response can lead to oxidative stress, apoptosis, and conditions such as diabetes, rheumatoid arthritis, cancer, and ischemia.To maintain homeostasis there are moderators of the inflammatory response. Binding of interleukin IL-1 to IL-1R1 stimulates the inflammatory cascade. Alternately, AF10847 binds to IL-1R1 resulting in significant conformational change of IL-1R1 but its lack of any cytokine activity locks IL-1R1 in an inactive state inhibiting a signalling event. AF10847 has an exceedingly high affinity for IL-1R1 compared to 1α and IL-1β.Extensive searches for lower molecular mass IL-1R antagonists-for oral delivery as a therapeutic for rheumatoid arthritis are being carried out. AF10847 is a 21-mer that has high affinity for the conserved IL-1R1 binding site that is also recognised by IL-1β. The remarkable high affinity of AF10847 for IL-1R1 makes it a perfect candidate for further investigations into novel IL-1R1 inhibitor development.

  • Influenza A NP (44-52) (HLA-A1)


    Influenza A NP (44-52) (HLA-A1) is a CEF control peptide that is derived from Influenza A. Influenza A is an enveloped negative-strand RNA virus that is capable of interfering with host transcription, which can ultimately cause cell death. The action of the virus particles decreases the downstream gene occupancy of RNA polymerase II, as well as instigating cellular stress, resulting in the failure of polymerase II termination at poly(A) sites. Influenza A NP (44-52) (HLA-A1) is defined as a CEF control peptide due to its antigenic properties. Clinically, this peptide is a suitable epitope for CD8+ T cells and can be used to stimulate the release of IFNg. HLA-A1 refers to the cell HLA type that this peptide acts on.The nucleoprotein (NP) is a structural protein that encapsulates the negative strand of viral RNA. NP plays a critical role in the transition of influenza virus RNA synthesis from transcription mode to replication mode.

  • SARS-CoV-2 NSP13 (581-595)


    The SARS-CoV-2 non-structural protein 13 (NSP13) has been identified as a target for anti-viral therapeutics due to its highly conserved sequence and is essential for viral replication.  NSP13 is part of the helicase superfamily 1B. As an NTPase and RNA helicase, NSP13 binds to RNA-dependent RNA polymerase and acts in concert with the replication-transcription complex to stimulate backtracking and further activate NSP13 helicase activity. These factors make NSP13 a good target for developing new antiviral drugs. In addition, the identification of epitopes within the NSP13 sequence can help design more effective SARS-CoV-2 vaccines.Models have predicted epitopes exhibiting antigenicity, stability and interactions with MHC class-I and class-II molecules. NSP13 (581-595) is an epitope candidate with various HLA restrictions. This epitope can be used to better vaccine design for more durable CD4+ and CD8+ T cell responses for long-lasting immunity.

  • Histone H3.3 (1-44)


    Histone H3.3 is a replication-independent histone variant, which replaces canonical histone H3.1/2 outside of S phase. H3.3 is expressed throughout the cell cycle, as well as in quiescent cells and is referred to as the 'replacement histone'. H3.3 is largely deposited in a DNA synthesis-independent fashion by a distinct set of chaperones proteins. H3.3 accumulates in post mitotic cells, such as cerebral cortical neurons and is incorporated at sites of UV damage where it protects against sensitivity to UV light. H3.3 deposition occurs on DNA sequences that are transiently nucleosome-free, such as during transcription and DNA repair, therefore serving as a marker for regions of high transcriptional activity. H3.3 is also enriched in heterochromatic subtelomeric and pericentromeric regions. H3.3 plays important roles in many developmental contexts such as in stem cells, during fertilization and reproduction and during reprogramming of genomes following fertilization or somatic cell nuclear transfer. Mutations in histone H3.3 are common events in certain cancers.

  • HLA-A*02:01 MAGE-A1 (278-286)


    HLA-A*02 is a class I major histocompatibility complex (MHC) allele which is part of the HLA-A group of human major histocompatibility complex (MHC) leukocyte antigens (HLA). HLA-A is a human MHC class I cell surface receptor and is involved in presenting short polypeptides to the immune system. These polypeptides are typically 7-11 amino acids in length and originate from proteins being expressed by the cell. Cytotoxic T cells in the blood "read" the peptide presented by the complex and should only bind to non-self peptides. If binding occurs, a series of events is initiated culminating in cell death via apoptosis. Melanoma-associated antigen 1 (MAGE-A1) is part of a well-characterized group of cancer/testis antigens (CTA) that are encoded as a separate cluster on the X chromosome. MAGE-I antigens are mainly expressed in highly proliferating cells, such as cancer cells and therefore may be ideal targets for cancer immunotherapy. Expression of MAGEs has been reported several types of cancer including: lung- breast- thyroid- colon- stomach- liver and bladder where MAGE-A is considered to be a poor prognostic factor.This peptide corresponds to part of the MAGE-A1 sequence which is presented on the MHC class I antigen HLA-A*02.

  • Gag peptide [Simian immunodeficiency virus]


    Simian immunodeficiency virus (SIV) has been used as a model in rhesus monkeys to understand human immunodeficiency virus (HIV) viral life cycle and lead towards drug development. HIV specific CD8+ T-cell (cytotoxic T lymphocyte (CTL)) responses are important in the control of viral replication. Inducing a sustained HIV-1 specific CD8+ T-cell response is the target for vaccine development by using conserved HIV-1 epitopes. The HIV gag gene encodes p17 and p24. Capsid protein p24 forms the conical core of the virus that encapsulates the genomic RNA-nucleocapsid complex. SIV encode a homologous Gag peptide, this allows use of rhesus monkey models to better understand the immune response to SIV/HIV.A CTL recognition epitope of SIV p24 Gag, residues TPYDINQML, activates the immune response. SIV Gag peptides have been used as effective epitopes in immunological assays to assess CTL response. Stimulation of rhesus monkey cells with TPYDINQML epitope triggers CD8+ T lymphocytes to produce soluble factors (β-chemokines) that inhibit SIV replication. Further work may lead towards a HIV vaccine using the Gag epitopes.

  • ANP (1-23)


    ANP (1-23) is derived from the atrial natriuretic peptide (ANP) which is a cardiac hormone involved in maintaining cardio-renal homeostasis. This occurs through the activation of the guanylyl cyclase-coupled receptor, resulting in the increased concentration of cyclic guanylate monophosphate. Moreover its function in the processes of anti-proliferation and anti-angiogenesis allow it to take part in cardiovascular remodelling.ANP is a member of the natriuretic peptide family and it is encoded by the NPPA gene, located on chromosome 1. Once synthesized from the 151 amino acid pre-prohormone into its biologically active form, ANP is secreted by the atrial cardiomyocytes in the circulating forms: ANP (1-98) and ANP (99-126). This synthesis process involves the signal peptide being removed from the pre-prohormone resulting in pro-ANP (1-126) which is converted into the circulating forms by the type II transmembrane serine protease Corin.

  • Tregitope 084


    T regulatory cell epitopes (Tregitopes) are a set of natural T cell epitopes derived from immunoglobulin G. These peptides are Treg-activating and show some promise in prophylactic and therapeutic studies in type 1 diabetes mellitus: which is associated with effector T cell (Teff) destruction of insulin-producing pancreatic β-islet cells. In non-diabetics, self-reactive T cells are deleted during thymic development, rendered anergic, or converted into natural regulatory T cells (Tregs) that suppress autoimmune responses.Tregitopes are processed and presented by MHC class II molecules. They can suppress effector T cell responses, and up-regulate Treg-associated cytokines and chemokines. Tregitopes help stimulate 'antigen-specific adaptive tolerance induction' (ASATI) to modulate antigen-specific transplant rejection and to reduce immune responses to allergens in vitro and in vivo. Tregitope 289 is also available in our catalogue.

  • Ig heavy chain variable region Light


    Peptide derived from the variable region on the heavy chain of immunoglobulin (Ig) which is part of the fragment antigen binding (Fab) fragment of antibodies. Ig or antibodies are made up of two heavy and two light chains both of which have a constant region and a variable region. The variable region, the antigen binding site, is composed of three complementarity determining regions (CDRs) from the variable heavy chain and three CDRs from the variable light chains. The amino acid sequences of the variable region differ between each antibody allowing Ig to bind to specific antigens.The variable regions are encoded by a variety of V, D and J gene segments. During somatic recombination different combinations from the V, D and J varieties can be joined together. Consequently this gives rise to a diverse variable region.The Ig heavy chain can be classed as being either: IgM, IgG, IgA, IgD or IgE each of which change the function of the antibody.

    PD-1 inhibitors and PD-L1 inhibitors are a group of checkpoint inhibitors being developed for the treatment of cancer.PD-1 and its ligand PD-L1 are critical in regulating T cell activation, tolerance and immunopathology. PD-1 is an immune checkpoint and guards against autoimmunity through two mechanisms. First, it promotes apoptosis of antigen-specific T-cells in lymph nodes. Second, it reduces apoptosis in regulatory T cells. Several types of cancer cells overexpress PD-L1 in order to escape from the PD-1/PD-L1 immunosurveillance mechanism. In this way, Human PD - L1 inhibitor V could be used in the treatment of cancers that overexpress PD-L1.

  • CRAMP-18


    Cathelicidin-related anti-microbial peptide (CRAMP), is the mouse homologue of the human LL-37 antimicrobial peptide and shares 67% sequence identity with LL-37.CRAMP-18 is the anti-bacterial sequence derived from CRAMP, it possesses potent anti-bacterial activity against Gram-positive and Gram-negative bacterial strains with no haemolytic activity. As well as displaying direct anti-microbial activity, CRAMP-18 also binds to lipopolysaccharide (LPS) to neutralise LPS activity.CRAMP is a cationic peptide, encoded for by the Camp gene and is highly expressed in bone marrow. Its expression is up-regulated by infectious and inflammatory signals and it is secreted by cells such as neutrophils, epithelial cells, and macrophages.

  • C-terminal Sortagging-[Cys(Sulfocyanine7)]


    This C-terminal Sortagging peptide acts as a (oligo)glycine nucleophile in the final steps of a sortagging protein labelling reaction. This reaction results in the (Sulfocyanine7) fluorescent moiety being attached to the C-terminus of the target protein or peptide.A substrate peptide containing the LPXTG motif is recognised and cleaved by the enzyme Sortase A (SrtA) from Staphylococcus aureus. The catalytic cysteine residue in the active site of SrtA, serves as a nucleophile to cleave the peptide bond between threonine and glycine of the substrate peptide. Cleavage results in the formation of a thioacyl intermediate between the substrate peptide and SrtA. This intermediate is then resolved by the N-terminus of this (oligo)glycine nucleophile peptide, resulting in the creation of a new peptide bond that links the substrate peptide to this peptide and its fluorescent dye.  This method of protein labelling is known as sortagging.This peptide contains Sulfocyanine7, which is a NIR (near infrared) emitting fluorescent dye.

  • EGFR/kinKDR peptide substrate


    Substrate of the epidermal growth factor receptor (EGFR), a member of the receptor tyrosine kinase family known as ErbBs or HER receptors. These receptors are involved in the regulation of cell proliferation, survival, differentiation and migration. However their dysregulation can contribute towards many diseases such as cancer.Binding to the ligand binding domain of the EGFR causes receptor dimerization. This is sequentially followed by the tyrosine kinase domain being activated and the tyrosines on the C-terminal tail become phosphorylated, which in turn activates downstream signalling pathways.

  • TAT 2-4


    TAT 2-4 is derived from human immunodeficiency virus (HIV) transactivator of transcription (TAT) residues 47-58. TAT (47-58) is a cell penetrating cationic peptide derived from the N-terminus of the Tat protein, which is a trans-activator of the transcription protein present in the human immunodeficiency virus (HIV). As a cell penetrating peptide (CPP) TAT aids in the cellular uptake of molecules and hence serves a valuable purpose in transduction methods. TAT 2-4 are residues (47-58) of HIV TAT protein repeated back to back, this dimer of TAT sequences has been shown to be the most efficient oligomer for cell penetration. This TAT dimer has been used in previous studies to deliver a wide variety of cargoes including fluorophores, chelators and DNA to target cells.
