VIP – High Purity Premium Neuropeptide API

Product Overview VIP (Vasoactive Intestinal Peptide) is a 28-amino-acid endogenous neuropeptide widely distributed in nervous system, respiratory tract and gastrointestinal tract. It binds to VPAC1 and VPAC2 receptors, featuring anti-inflammation, airway smooth muscle relaxation, gastrointestinal mucosa protection, microcirculation dilation and immune regulation effects. It inhibits excessive secretion of pro-inflammatory factors such as TNF-α and IL-1β, relieves neurogenic inflammation, repairs vascular endothelial injury and regulates immune balance without obvious immunosuppressive side effects.

It is applied in laboratory research including neuroinflammation intervention, airway remodeling research, gastrointestinal mucosal injury repair, endothelial protection, immune homeostasis regulation and neuropeptide receptor pharmacodynamic verification. It is extensively adopted in inflammatory signaling pathway exploration and neuropeptide pharmacology experiments.

Adopting optimized solid-phase peptide synthesis and chromatographic refining technology, the product has excellent water solubility and stable biological activity after reconstitution with designated solvent. CAS Number: 40077-57-4
