Description
Product Description
VIP peptide, also known as vasoactive intestinal peptide, is a neuropeptide composed of 28 amino acids and is extensively studied in neurotransmission, smooth muscle relaxation mechanisms, immune modulation pathways, and receptor-mediated signaling research. Due to its well-characterized molecular structure and broad physiological relevance, VIP peptide serves as an important reference peptide in neuroendocrine and gastrointestinal research models.
This VIP peptide product is supplied as a lyophilized powder in sterile glass vials, ensuring excellent stability, long-term storage capability, and reliable reconstitution performance for laboratory use. The peptide is synthesized using advanced solid-phase peptide synthesis technology and purified through multi-step chromatographic processes to achieve high batch consistency. Each production batch is supported by a Certificate of Analysis (COA) and full analytical documentation.
In research applications, VIP peptide is commonly utilized in studies involving vasodilation mechanisms, smooth muscle receptor signaling, neuroimmune interaction pathways, inflammatory modulation models, and peptide receptor binding investigations. Its receptor selectivity and biological activity make it a valuable tool for both in vitro assays and exploratory preclinical research.
VIP peptide is intended strictly for research and laboratory use only. It is not approved for therapeutic, diagnostic, or veterinary applications.
