| Description | Vasoactive intestinal peptide (VIP) is a 28-aminoacid peptide (human, chr 6q26-q27). Expressed and secreted by neurons innervating primary and secondary immune organs such as lymph nodes with a Mol.wt of 20kD. VIP is a potent neurotrophic factor causes vasodilation, lowers arterial blood pressure, and relaxes the smooth muscle of trachea, stomach and gall bladder. VIP also modulates several T-lymphocyte activities including motility, cytokine production, proliferation and apoptosis, VIP exerts its biological activity by binding to two closely related class II G-protein-coupled receptors VPAC-1 and VPAC-2 beside this VIP has its own receptors VIPR1&2 (Vasoactive Intestinal Polypeptide Receptor 1&2) and VIPRRP (VIP receptor-gene repressor protein). VIP shows similarities to glucagon, secretin and gastric inhibitory peptide (GIP) as such it has been considered a member of the glucagon-secretin family. The VIP is 100% conserved in mouse, rat and human. VIP is considered to be a viable candidate for the development of treatments for rheumatoid arthritis, since treatment with VIP significantly reduced incidence of severity of arthritis, the therapeutic effect of VIP was associated with downregulation of both inflammatory and autoimmune components of the disease. VIPR1 is a 457aa (chr. 3p22) glycosylated receptor in human (459aa in rat, 459aa in mouse) has a signal peptide sequence with several transmembrane domains. The VIP receptor 1 is also termed as type II PACAP receptor, RCD1. It is predominantly expressed in cholinergic presynaptic neurons of the central nervous system and in peripheral peptidergic neurons innervating diverse tissues. The Highly conserved aspartate 68, tryptophan 73 and glycine 109 in the N-terminal extracellular domain of the human VIP receptor are essential for its ability to bind VIP. VIPR1 appears in two isoforms, a long form/ hIVR5 and a short form/ hIVR8 formed after alternative splicing. Source: 17aa peptide from Mouse VIPR (1) Location: ~N-terminus Species Sequence Homology: Rat-100%; Human-90%. Applications: Suitable for use in ELISA as a control peptide for V2115-20N. Other applications not tested. Recommended Dilution: ELISA: Coat ELISA plates at 1ug/ml Optimal dilutions to be determined by the researcher. Storage and Stability: Lyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute with sterile buffer or ddH2O. Aliquot to avoid repeated freezing and thawing. Store at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer. | ||
