Description

Vasoactive Intestinal Peptide (7-11) CAS NO 107531-14-6 is a specific, biologically active fragment of the full-length vasoactive intestinal peptide (VIP), comprising amino acid residues 7 through 11. This peptide fragment is a critical research tool for studying VIP receptor interactions, signal transduction pathways, and the localized physiological effects of the parent hormone. It is primarily utilized by pharmaceutical R&D teams, academic researchers, and biotechnology companies engaged in neuroendocrinology, immunology, and cardiovascular research.

Application

• Neuroscientific Research: Investigation of VIP's role in neurotransmission, neuroprotection, and circadian rhythm regulation.
• Immunology Studies: Exploration of anti-inflammatory and immunomodulatory properties mediated by VIP receptor subtypes.
• Cardiovascular Research: Study of vasodilation, smooth muscle relaxation, and cardiac function modulation.
• Drug Discovery & Development: Used as a reference standard, pharmacophore model, or lead compound in designing novel peptide-based therapeutics.
• Biochemical Assay Development: Serves as a key reagent in receptor binding assays, enzyme-linked immunosorbent assays (ELISAs), and functional cellular assays.
• Academic & Clinical Research: Fundamental studies on gastrointestinal physiology, metabolic regulation, and endocrine system interactions.
