Peptidi
I peptidi sono catene corte di amminoacidi legate da legami peptidici, che svolgono ruoli chiave come molecole biologiche importanti nei processi cellulari. Funzionano come ormoni, neurotrasmettitori e molecole di segnalazione, e sono ampiamente utilizzati in applicazioni terapeutiche e diagnostiche. I peptidi sono anche cruciali nella ricerca per lo studio delle interazioni proteiche, delle attività enzimatiche e dei percorsi di segnalazione cellulare. Presso CymitQuimica, offriamo una vasta selezione di peptidi di alta qualità per supportare le vostre esigenze di ricerca e sviluppo in biotecnologia e farmacologia.

SPA4 is a surfactant protein-A (SP-A)-derived peptide which is an antagonist of toll-like receptor-4 (TLR4). SP-A and TLR4 have been identified as important pathogen-pattern recognition receptors (PPRRs). SP-A represents the majority of SPs and plays a key role in fighting pathogens and down-regulating inflammation, whereas TLR4 recognises pathogens and endogenous stress proteins and induces the inflammatory and adaptive immune responses.Over-activation of TLR4 induces inflammatory response via NF-KB and TNF-α cytokine. SPA4 has been shown to bind to TLR4 and inhibit the release of TNF-α in response to the most potent TLR4-ligand: Gram-negative bacteria-derived lipopolysaccharide (LPS), however SPA4 does not interfere with LPS binding to TLR4. The suppression of LPS-TLR4 signalling by SPA4 peptide alleviates inflammatory response.Peso molecolare:2,396 g/molAc-RRRRRRRRRRRR-OH

BAM (8-22), the Bovine adrenal medulla 8-22 peptide is synthesised from proekephalin after it has undergone proteolytic cleavage. It can induce what is known as the 'itching' or 'scratching' response through activating, using an opioid independent mechanism, the G-protein coupled receptor MRGPRX1. This subsequently activates the Gαq/11 pathway and the cation channel TRPA1 histamine independent itch pathways.It is believed that BAM 8-22 can contribute to chronic itching in diseases such as cholestasis-related pruritus, in which patients are commonly diagnosed as having a reduction in bile flow.Peso molecolare:1,971.2 g/molHXB2 gag NO-26

CAS:Purotoxin-1 is a peptide that belongs to the group of activators. It is an inhibitor of potassium channels which are involved in the regulation of excitability and repolarization of cells. Purotoxin-1 has been shown to block the binding of calcium ions to the N-type voltage-gated calcium channels, leading to decreased intracellular calcium levels and reduced neurotransmitter release. Purotoxin-1 has been shown to inhibit tumor growth in vivo, which may be due to its ability to inhibit protein interactions with cell surface receptors.Formula:C155H248N50O48S8Purezza:Min. 95%Peso molecolare:3,836.5 g/molH-Gln-2-ClTrt-Resin (100-200 mesh) 1% DVB

Flu mp 58
CAS:Portion of Influenza MFormula:C49H75N9O11Colore e forma:PowderPeso molecolare:966.18 g/molClick (AAKK)4
Small peptide design has become of interest to catalyse chemical transformations within the cell. The aim is to generate peptides to enhance the hybridization of attached oligonucleotides to complementary DNA sequences. (AAKK)4 is modelled on the surface of staphylococcal nuclease, it a short cationic lysine-rich peptide that can deliver a nucleophile to DNA or RNA. (AAKK)4 peptide can improve DNA-PNA (peptide nucleic acid) hybridisations dramatically as well as increase strand invasion rate. (AAKK)4 peptide is a non-lipid approach for cell penetration which is preferable for certain cell lines due to cytotoxicity issues. (AAKK)4-antisense conjugates have been used to silence gene expression.(AAKK)4 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-(AAKK)4 allows a wide variety of applications particularly for conjugation, modification, and peptide design.

Myelin Basic Protein (MBP) (68-82), guinea pig
The 14 amino acid fragment of myelin basic protein (MBP) (68-82) can induce experimental allergic encephalomyelitis (EAE) in Lewis rats. EAE is the most used experimental model for studying the human inflammatory demyelinating diseases, such as multiple sclerosis (MS).MBP is an integral component of myelin found in the central nervous system (CNS). MBP is considered vital for the development and stability of the myelin sheath where it plays a role in membrane adhesion. MPBs constitute an extraordinarily varied collection of splice isoforms which show a myriad of post-translational modifications. MBP may be targeted by auto-antibodies in diseases such as MS. Use of MBP fragments in immunology assays are helping to answer this. The low affinity of MBP (1-9) peptide for major histocompatibility complex (MHC) class II molecules may result in MBP autoreactive T cells escaping central-tolerance, where self-reactive T cells are usually eliminated. The activity induced by MBP (68-82) suggests it can cause EAE but other EAE MBP peptides were found to induce a stronger response. The MBP (68-82) and others available in our catalogue may help to understand the nature of demyelinating diseases and find the target autoantigens of conditions such as MS.Colore e forma:PowderPeso molecolare:1,735.8 g/molHRKy peptide
HRK-Y is a synthetic BH3 peptide that selectively antagonizes BCL-XL, a pro-survival protein of the Bcl-2 family. This interaction disrupts the balance of Bcl-2 family proteins, leading to cytochrome c release and subsequent apoptosis in susceptible cancer cells. HRK-Y is utilized in BH3 profiling assays to assess the sensitivity of cancer cells to BH3-mimetic drugs and to identify potential synergistic effects with NK cell-based therapies.Vasoactive Intestinal peptide

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.Peso molecolare:1,930.9 g/molH-TLSDYNIQK^-OH

Antennapedia peptide
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 CPP, 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. Penetratin is provided here as a C-terminal acid but is also available in amide form.Peso molecolare:2,246.73 g/mol(Des-Glu22)-Amyloid β-Protein (1-42) trifluoroacetate
