Peptide H-WVDGTDYETGFK^-OH is a Research Peptide with significant interest within the field academic and medical research. This peptide is available for purchase at Cymit Quimica in multiple sizes and with a specification of your choice.[Azhx]-ANP (Human)
ANP (human) 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.At the N-terminus Azhx, 6-azidohexanoic acid, is present.

Heat shock proteins (Hsps) are highly conserved and stress inducible. Hsp70 has been found in tumour cell lines to be highly expressed with a higher plasma membrane localisation. This is correlated to the cell sensitivity to natural killer (NK) cell-mediated lysis. Investigation identified that Hsp70 N-terminal extended peptide TKD (450-463) was critical for this to occur. TKD (450-463) with low dose interleukin (IL-2) has the same capacity to induce NK cell proliferation and activity as the full-length protein Hsp70. Excess of Hsp70 and TKD (450-463) both inhibit cytolytic activity by NK cells. Other related sequences tested did not lead to NK cell-mediated lysis. Further study with the TKD (450-463) epitope could elucidate how NK cells are activated by Hsp70s as the mechanism remains unclear.Peso molecular:1,562.8 g/molTAT-TRPV1 (736-745)
TAT-TRPV1 (736-745) is a cell-permeable TRPV1 fragment (capsaicin receptor and the vanilloid receptor 1), that can inhibit the interaction of TRPV1 and A-kinase anchoring protein 79 (AKAP79). TAT- TRPV1 (736-745) consists of amino acids 736-749 from the TRPV1 C-terminal domain, combined with amino acids 47-57 of TAT to promote uptake across neuronal cell membranes. TAT-TRPV1 (736-745) inhibits both the first and the second phase of pain behaviour in the formalin test, implying an effect on both acute and inflammatory pain.A-kinase anchoring protein 79 (AKAP79) is a protein that targets kinases to TRPV1. Inflammation causes hyperalgesia but can be reduced when TRPV1 is blocked. a key region on AKAP79, amino acids 326-336, is responsible for its interaction with TRPV1. TAT-TRPV1 (736-745) promotes uptake across the cell membrane and TRPV1 (736-745) inhibited inflammatory hyperalgesia in mice. TAT-TRPV1 (736-745) did not affect pain thresholds in the absence of inflammation. These results suggest that antagonizing the TRPV1-AKAP79 interaction will be a useful strategy for inhibiting inflammatory hyperalgesia and TAT is an effective delivery system.

[Sar1]-Angiotensin II
CAS:Producto controladoAngiotensin II is a peptide hormone that is secreted by the kidneys. It stimulates the release of aldosterone and causes vasoconstriction, leading to an increase in blood pressure. Angiotensin II is also involved in other physiological functions such as the regulation of fluid balance, electrolyte levels, and blood coagulation. The drug is used to treat congestive heart failure and high blood pressure. Sar1-Angiotensin II has been shown to inhibit transcriptional regulation by binding to the angiotensin receptor type 1 (AT1). This binding disrupts conformational changes in the receptor, preventing signal transduction from occurring and decreasing the activity of enzymes such as protein kinase A, which are needed for activation of transcription factors.Fórmula:C49H71N13O10•(C2H4O2)2Pureza:Min. 95%Peso molecular:1,122.28 g/molMBP Ac1-9 (4Y)
This peptide constitutes the acetylated N-terminal region of murine myelin basic protein (MBP) and displays high affinity for major histocompatibility complexes (MHC). This high MHC affinity is due to substitution of the native lysine at position 4 for a tyrosine. Substitution increases the MHC binding affinity of the peptide by around 1 million fold, therefore creating a superagonist ligand. MBP is an integral component of myelin found in the central nervous system (CNS) vital for the development and stability of the myelin sheath where it plays a role in membrane adhesion. MBP may be targeted by auto-antibodies in diseases such as multiple sclerosis. The low affinity of the native lysine containing MBP 1-9 peptide for MCH class II may result in MBP auto-reactive T cells escaping central-tolerance where self reactive T cells are usually eliminated. MBPs constitute an extraordinarily varied collection of splice isoforms which show a myriad of post-translational modifications.

Peso molecular:1,906.3 g/molInsulin A Chain (A12-21)
Type I diabetes is an autoimmune condition caused by the destruction of insulin-producing β cells. The initiation mechanism is unclear but involves activating autoreactive T cells against the β-cell-specific antigen, insulin.RIP-B7.1 mice express CD80 on pancreatic β cells and are a model for studying de novo induction of diabetogenic CD8 T cells. Immunization of RIP-B7.1 mice with preproinsulin (ppins)-encoding plasmid DNA induces experimental autoimmune diabetes (EAD). EAD is associated with significant induction of CD8 T cells specific for the (A12-21) restricted epitope leading to the destruction of β cells.The Insulin A Chain (A12-21) epitope is recognised by pancreas-infiltrating CD8 T cells isolated from immunized, diabetic RIP-B7.1 mice as shown by flow cytometry. The Insulin A Chain (A12-21) epitope can also be used to stimulate inducible IFN- expression of ppins-primed CD8 T cells ex vivo as determined by flow cytometry. GFP fusion has shown the expression of insulin A chain (A12-21) epitope in HeLa cells.Peso molecular:1,246.3 g/molAoa-KRRGSTCVLA-NH2

Thrombin is the main effector of the coagulation cascade- it is a serine protease. Thrombin binds to active protease activated receptor 1 (PAR-1) which belongs to a subfamily of G-protein coupled receptors (GPCR). However, thrombin generated during cardiopulmonary bypass can activate PAR-1 leading to platelet dysfunction and unwanted bleeding. FLLRN is found to be a potent PAR-1 antagonist. Use of FLLRN and variants has aided the study of platelet aggregation dynamics. Further study may provide a suitable clinical application.Peso molecular:661.4 g/molLeu-Ile-Thr

Albumin (51-62) Bovine
Albumin (51-62) Bovine is derived from the globular protein Albumin and is found in the blood plasma of humans (known as Human Serum Albumin, HSA) where it serves to maintain plasma pressure and nutritional balance. Another role it carries out is the transportation of bound molecules through the blood. Bovine serum albumin (BSA), composed of 583 amino acids, is very similar to HSA thus allowing BSA to be used as a successful model and a standard protein in laboratory experiments.Although BSA and HAS share homology in their three domains, I, II and III, BSA contains 2 tryptophan whereas HAS only contains 1 tryptophan residue.In agriculture the presence of the albumin protein has been used to assess the health of cows to ensure that a suitable quality of milk and meat are produced. Moreover it is important to detect bovine albumin in food and pharmaceutical products due to it being an allergenic protein.Forma y color:PowderPeso molecular:1,510.8 g/molH-YSTDVSVDEVK^-OH

Biotinylated L57
The blood-brain barrier (BBB) is a major obstacle to drug delivery into the central nervous system (CNS), in particular for macromolecules such as peptides and proteins. However, certain macromolecules can reach the CNS via a receptor-mediated transcytosis (RMT) pathway, and low-density lipoprotein receptor-related protein 1 (LRP1) is one of the promising receptors for RMT. Recent studies have shown that biotinylated L57 binds to LRP1 (CL4)-Fc more efficiently than Angiopep-7 (a different LRP1 ligand), which might explain the improved BBB permeability of L57.Peso molecular:3,110.6 g/molHXB2 gag NO-55/aa217 - 231
