Biotin-Substance P
Substance P (SP) is a peptide that is highly conserved across the animal kingdom and is involved in a number of inflammatory and growth promoting processes. SP has a net positive charge at physiological pH, it is an amphiphilic peptide with positively charged residues at the N-terminus and hydrophobic residues at the C-terminus, this controls how it interacts with cell membranes. SP is stable in plasma (several hours) but has a short half-life in tissues (seconds/minutes).SP is encoded by the TAC1 gene and is a member of the tachykinin peptide hormone family. SP is expressed by many cell types including: neurons, astrocytes, microglia, epithelial cells, endothelial cells, immune cells such as T cells and macrophages- dendritic cells and eosinophils and some stem cells and progenitor cells. The huge variety of cell types expressing SP suggest it is involved in a wide variety of physiological and pathophysiological functions.SP mediates its functions by interacting with members of the neurokinin (NK) family of G protein-coupled receptors with high selectivity. Among these, SP binds to NK1R with the highest affinity, this receptor is expressed in a wide range of tissue types.Biotin (B7) has been added to the N-terminus.Formula:C73H112N20O15S2Peso molecolare:1,573.96 g/molbeta-Casomorphin (1-2)
CAS:Beta-casomorphin (1-2) is a peptide that has been identified as a possible endogenous ligand for opioid receptors. It is a product of the breakdown of casomorphin, a milk protein found in dairy products such as cheese and yogurt. Beta-casomorphin (1-2) has been shown to bind to human immunodeficiency virus type 1 receptors and may play an important role in the pathogenesis of human immunodeficiency virus type 1 infection. This peptide also inhibits bacterial growth by binding to bacterial ribosomes, preventing the formation of new proteins, which leads to cell death. Beta-casomorphin (1-2) has been shown to have an inhibitory effect on blood pressure and its antihypertensive activity may be due to its ability to stimulate the release of nitric oxide from endothelial cells.Formula:C14H18N2O4Purezza:Min. 97 Area-%Colore e forma:PowderPeso molecolare:278.3 g/molAc-TPSLPTPPTR-NH2

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.Peso molecolare:2,564.3 g/mol
