VIP..

VIP (Vasoactive Intestinal Peptide), CAS No. 40077-57-4, is a 28-amino-acid peptide naturally occurring in the nervous system and various peripheral tissues. It is widely studied for its involvement in cellular signaling, neurobiology, immune regulation, smooth muscle activity, and vascular biology. VIP primarily exerts its biological effects through interaction with VPAC1 (VIPR1) and VPAC2 (VIPR2) receptors, making it an important research target in peptide pharmacology, receptor studies, signal transduction, neuroscience, and immunology.

This product is supplied as a research-grade peptide material and may be used for laboratory research, analytical method development, reference standard studies, in vitro experiments, and other life science applications. The typical amino acid sequence of VIP is His-Ser-Asp-Ala-Val-Phe-Thr-Asp-Asn-Tyr-Thr-Arg-Leu-Arg-Lys-Gln-Met-Ala-Val-Lys-Lys-Tyr-Leu-Asn-Ser-Ile-Leu-Asn-NH2, with a C-terminal amide structure and a molecular weight of approximately 3325.8 Da.

Product specifications, including purity, peptide content, salt form, appearance, packaging, storage conditions, and analytical data, may vary by batch and should be confirmed according to the applicable Certificate of Analysis (COA) and technical documentation.
