  • CA-074

    CAS:
    <p>CA-074 is a research tool that can be used to study protein interactions. CA-074 is a small, synthetic peptide and a potent inhibitor of the ion channel TRPC1. It has been shown to inhibit the calcium currents in HEK293 cells expressing TRPC1 channels. CA-074 inhibits the kinase activity of PLCγ2, which leads to reduced phosphoinositide levels and a decrease in cell proliferation. CA-074 also inhibits PKCδ and PKCε, which are members of the protein kinase C family.<br>The inhibition of these enzymes by CA-074 causes an increase in the intracellular concentration of diacylglycerol (DAG) and inositol triphosphate (IP3). These two molecules are involved in G protein signaling pathways that regulate cell proliferation, differentiation, and survival.</p>

  • nef protein fragment (Acetyl/amide) [Human immunodeficiency virus 1]


    <p>Nef is an accessory protein highly conserved amongst all primate lentiviruses, it is essential for viral replication in vivo- it is expressed by human immunodeficiency virus (HIV) HIV-1 and HIV-2. Nef acts as a downregulator of class I human leukocyte antigens (HLA) expression in HIV-infected cells to help circumvent the immune response, such as Cytotoxic T lymphocytes (CTL) activity. An intact nef gene is critical for high viral loads, linked to development of acquired immunodeficiency syndrome (AIDS). Certain alleles of HLA have been associated with maintaining a seronegative status such as HLA-A*1101.This nef peptide sequence contains the region considered to be a a C-proximal adaptor-protein (AP) interaction site. The presence of various nef motifs such as this are an intense area of investigation to understand if they are a factor in patients who remain clinically asymptomatic. This nef fragment is provided with an N-terminal acetyl group to increase its stability.</p>

  • SARS-CoV-2 Nucleoprotein (353-370)


    <p>The coronavirus (CoV) nucleoprotein is the major component of CoV structural proteins. Also known as the nucleocapsid protein, it is an abundant RNA-binding protein critical for viral genome packaging. These factors make nucleoprotein a good target for developing new antiviral drugs. In addition, the identification of epitopes within the nucleoprotein 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. Nucleoprotein (353-370) 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.</p>

  • survivin (baculoviral IAP repeat-containing protein 5) (21-28)


    <p>Survivin is an intracellular tumour-associated antigen that is part of the inhibitor of apoptosis (IAP) family. Survivin expression increases as cells age but becomes over-expressed in cancer cells. Expression is also important during embryonic development and tissue regeneration. With roles in aging, apoptosis, and cancer, there is considerable interest in understanding the function of Survivin. Survivin expression is regulated by TGF-β and increased following intestinal inflammation during the healing process.The high expression of Survivin in cancer cells has led to the search for a vaccine that induces epitope-specific CD8+ T cells. The epitope TFKNWPFL restricted to H-2 Db was identified using prediction algorithms and MHC class I binding assays. The epitope was delivered to mice by intradermal electroporation (EP). The Survivin epitope induced a  CD8+ cytotoxic T lymphocyte (CTL) response as shown by IFN-staining- they also showed an activated effector phenotype as CD44 and CD107 were upregulated. The Survivin vaccine was able to confer protection against melanoma in mice and suppress angiogenesis. This Survivin epitope could be a vital step in creating a human vaccine that generates CD8 CTLs with specific functional cytotoxic activity against tumour cells.The sequence provided here aligns to residues 21-28 of the Survivin epitope, the initial residue of the epitope has been omitted as it is not conserved between mice and human sequences.</p>

  • Neuropeptide S human


    <p>Neuropeptide S (NPS) is a neuropeptide found in mammalian brains, primarily in neurons in the lateral parabrachial nucleus, the peri-locus coeruleus and the principle sensory 5 nucleus of the trigeminus. NPS in involved in several neuroendocrine, behavioural and inflammatory responses, including: reducing anxiety in mice- suppressing appetite and inducing wakefulness and hyperactivity. NPS treatment can be used to improve fear extinction in mice and limit fear memory retrieval after fear reduction training, thus making it an interesting target for treatment of post-traumatic stress disorder. NPS exerts its actions by binding to a G-protein coupled receptor, NPSR.</p>

  • Compstatin


    <p>The cyclic tridecapeptide Compstatin, binds to and selectively inhibits the interaction between C3 and convertase, hence preventing the formation of C3a and C3b and activation of the complement system. Compstatin has the ability to form β-turns and hydrophobic clusters which are crucial for its inhibitory properties. When binding between C3 MG4 and MG5 domains, located within the MG-ring of the β-chain, Compstatin undergos a conformational change which is believed to prevent C3 from binding to C3 convertase through steric hindrance. Consequently the complement cascade is inhibited.The complement cascade is an important feature of the immune system. C3b, produced from the interaction of C3 and C3 convertase, binds to pathogens and somatic cells and signals for their removal from the body. However the increased activation of the complement system can result in diseases, associated with Alzheimers, strokes, heart attacks and autoimmune diseases. Therefore Compstatin can be used as a therapeutic agent within medicine.</p>

  • TAT-AKAP79 (326-336) scrambled amide


    <p>The activation of transient receptor potential cation channel subfamily V member 1 (TRPV1) is believed to play a role in hyperalgesia, asthma and hypertension. TRPV1 is important for neuronal pain detection as well as the detection of heat, capsaicin, protons and the neurotransmitter anandamide.- The scaffold protein AKAP79 targets kinases to phosphorylate TRPV1, however it has been shown that inflammatory intermediates prostaglandin-E2 or bradykinin can activate these kinases creating a route for inflammation to cause hyperalgesia.This product is composed of the TRPV1 interacting residues of AKAP79 reordered into a scrambled sequence and conjugated to the cell penetrating TAT domain at the N-terminus. The scrambled peptide was shown in vivo to have no effect on TRPV1 algesia and thus is a vital control for research work. This product is a vital tool for research into suitable TRPV1 antagonists. The scrambled-TAT peptide is available for purchase in both an acid and amide form, this is the C-terminal amide form.</p>

  • TAT-CN21


    <p>TatCN21 is an inhibitor peptide for the calcium/calmodulin-dependent protein kinase II (CaMKII), a ubiquitously-expressed multifunctional serine/threonine protein kinase. TatCN21 blocks both autonomous and stimulated CaMKII activity with high selectivity. CaMKII is highly expressed in brain tissue where it regulates several processes including: neurotransmitter synthesis/release, neuronal plasticity- excitability and calcium homeostasis. Glutamate clearance by astrocytes is an essential part of normal excitatory neurotransmission, and accumulation of glutamate in the central nervous system is associated with many neurodegenerative disorders. CaMKII regulates glutamate homeostasis: CaMKII inhibition results in diminished glutamate uptake, dysregulated calcium homeostasis, release of the gliotransmitter ATP and compromise neuronal survival. Loss of CaMKII signalling may be an important factor in excitotoxicity. Peptide was obtained by linking the 11 amino acid human HIV Tat transporter to a 21 amino acid sequence corresponding to the CN21.</p>

  • Pep63


    <p>Soluble amyloid-β (Aβ) oligomers are key to Alzheimer's disease (AD) pathology. Aβ oligomers constitute a significant component of senile plaques, and the presence of plaques is used to define AD.  Soluble Aβ is the most neurotoxic species- its presence correlates with AD onset and early progression. There is no current treatment to prevent the formation of neurotoxic Aβ oligomers. A proposed strategy to treat AD is the inhibition of Aβ oligomer interacting with the NMDA receptor. Disruption of NMDA receptor function and signalling molecules affect neuronal plasticity and development.Pep63 was identified via peptide array to block the interaction between Aβ oligomers and EphB2. Mouse AD model stereotactic administration of Pep63 into the dorsal hippocampus blocked the interaction between Aβ and EphB2, as shown by co-immunoprecipitation and Western blotting. Reduced Aβ presence was detected following Pep63 treatment seen by ELIZA. Pep63 effectively reverses impaired memory deficits determined by the Morris water maze (MWM) on the AD mouse model.</p>

  • Azhx-Penetratin


    <p>Identification of cell penetrating conjugates has aided numerous areas of scientific development. The Drosophila transcription factor Antennapedia contains a homeodomain that can be internalised by cells to the cytoplasm and to the nucleus in a receptor-independent mechanism. The key residues for internalisation have been sequenced (RQIKIWFQNRRMKWKK), named penetratin, and used in several studies to aid entry of fusion proteins into cells.The full 60 amino acid homeodomain was fused to a T cell epitope of the influenza nucleoprotein and successfully internalised into T cells for presentation. The fragment known as penetratin was fused to a ligand for Grb-2 resulting in inhibition of downstream Grb-2 signalling events.- Penetratin has also been used in vivo to prime cytotoxic T lymphocytes by conjugating short antigenic peptides to the CPP. This penetratin has been synthesised with an N-terminal 6-azidohexanoic acid (Azhx) which can be used for various applications as a linker.</p>

  • dfTAT


    <p>Cell-penetrating peptides  (CPP) conjugated to biomolecular cargo can provide targeted molecular treatments. This could be revolutionary for numerous conditions such as cancer, muscular dystrophy and many more. CPP often use the endosomal system to enter the cell. Still, they vary in their ability to escape the endosome allowing the cargo to reach its intended area within the cell. Most CPP activity escaping the endosome is weak, and the method is unclear.Dimeric fluorescent TAT (dfTAT) is a CPP composed of 2 TAT peptides with an N-terminal fluorophore tetramethylrhodamine. When incubated with cells, it shows a cytosolic localisation. A simple co-incubation method of dfTAT with a cargo results in efficient endosomal leakage and release of the cargo to the cytosol. dfTAT has been shown to efficiently deliver a wide variety of cargos to the cell, including transcription factors, antibodies, and metal-organic framework (MOF) nanoparticles. One of the significant advantages of using dfTAT is that the co-incubation method of delivery allows dfTAT, and the cargo can be added as separate entities. This enables the controlled titration of material into cells through the modulation of cargo concentration independent of dfTAT.</p>

  • SARS-CoV-2 NSP13 (326-340)


    <p>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 (326-340) 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.</p>

  • Click Arg9


    <p>Cell penetrating peptides (CPP) are a keen area of molecule design to create the ideal vector for transporting macromolecule cargo into the cell. There is also a crossover of CPP acting as antimicrobial peptides (AMP) due to their ability to permeabilise the lipid membrane. AMPs are now being considered as a tool against the rise of antibiotic-resistant bacteria. CPPs and AMPS tend to be 10 - 30 amino acids long, cationic, and rich in arginine (R) and tryptophan (W). The presence of R and W in the backbone have been used to generate de novo CPP/AMP peptides with improved functions. Of these, nonarginine (R9) was shown to have the highest cellular uptake against other CPPs tested, lowest cytotoxicity and significant antimicrobial activity.R9 is provided here with a N-terminal alkyne attachment. Two of the most regularly encountered functional groups for click chemistry are azides and alkynes, and the azide-alkyne cycloaddition has become the most popular click reaction. The use of click chemistry with alkyne-R9 allows a wide variety of applications and has already been used for conjugation, modification and peptide design.</p>

  • BIM 187


    <p>Bombesin/GRP receptor agonist derived from the pro-apoptotic protein BIM, which is a member of the BCL-2 family proteins and activates the BAX and BAK proteins to promote apoptosis.The process of apoptosis can be activated by the intrinsic or extrinsic pathways, the former is activated by stress stimuli such as DNA damage and nutrient deficiency, while the latter is induced through activation of the death receptors FAS and TRAIL.The BCL-2 family's transmembrane anchor at the C-terminus allows them to locate at the mitochondrial outer membrane and play a vital role in apoptosis.Within the mitochondria BIM is a member of the BH3 molecules alongside, BIM, PUMA and NOXA which can all be activated by the intrinsic pathway. These in turn can initiate the homo-oligomerisation of BAX and BAK which induce mitochondrial outer membrane permeabilisation (MOMP) and the release of cytochrome c into the cytosol. Here cytochrome c associates with APAF-1 and dATP, ultimately activating effector caspase3/7 and apoptosis.BIM can be activated by CHOP-mediated transcription and phosphatase 2A-mediated dephosphorylation during endoplasmic reticulum stress. However when BIM is phosphorylated it undergoes degradation by the proteasome.</p>

The neurotoxins produced by Clostridium tetani are among the most potent molecules known to humankind. Once in the body, the toxin binds to the basal lamina at the neuromuscular junction. From here, the toxin is transported to inhibitory interneurons in the spinal cord, where it prevents the release of neurotransmitters, which causes spastic paralysis.</p>

  • Cecropin-B

    CAS:
    <p>Cecropins are a lytic peptide family, originally isolated from Hyalophora cecropia. Cecropin-B is a cationic helical peptide that can form pores, this is believed to be the reason for its such potent lytic activity. Cecropin-B has been shown to be effective against both Gram-positive and Gram-negative bacteria plus numerous cancer cell lines including multidrug-resistant types. The ability to insert into the cell membrane and lead to pore formation is attributed to the amphipathic groups present creating amphipathic regions. The effectiveness of cecropin-B on cancer cells has led to further use of the peptide as a model for potential new anticancer drugs including cyclic cationic forms.</p>

  • Apolipoprotein KV domain (67 - 77)


    <p>Vascular lipid deposition and altered lipid profiles are typical when unregulated angiogenesis is occurring, it is often seen in vascular disorders such as cancer and atherosclerosis. Apolipoprotein a (ApoA) functions as part of the lipid transporter complex high-density lipoproteins (HDL) to ensure lipid homeostasis and therefore the balance of angiogenesis. Within ApoA the Kringle5 (KV) domain (67 - 77), also known as KV11, has been identified as the region of ApoA that exerts anti-angiogenic effect. KV11 was shown in tumour cells to inhibit angiogenesis and consequently inhibits tumour progression. KV11 targets the angiogenesis c-Src/ERK pathway by blocking the activation signals received from vascular endothelial growth factor (VEGF). KV11 provides a new research potential for an anti-angiogenesis and anti-tumour therapeutic agent.</p>

  • Big Endothelin-3 (Human, 1-41 Amide) Acetate

    CAS:
    <p>Big Endothelin-3 (Human, 1-41 Amide) is a precursor molecule of the Endothelin-3 (ET-3) peptide, that belongs to the large family of endothelin peptides which activate the G-protein coupled receptors ETA and ETB. However ET-3 has lower affinity for the ETA receptors compared to Endothelin-1 (ET-1) and Endothelin-2 (ET-2), whereas all three endothelins have similar affinity for ETB receptors. As ETB receptors make up around 90% of the endothelin receptors found in the cerebral cortex in humans, ET-3 can be nicknamed the ‘brain endothelin’. Also through ET-3’s activation of ETB receptors, ET-3 is involved in the development of the enteric nervous system which controls within the gut, blood flow, secretion and intestinal motility. This product has disulfide bonds between Cys1-Cys15 and Cys3-Cys11.</p>
