Product Overview

Vasoactive Intestinal Peptide (VIP) is a naturally occurring neuropeptide composed of 28 amino acids and widely studied for its roles in cell signaling, vasodilation, and immune modulation.
In research contexts, VIP has demonstrated significant effects on cyclic AMP production, smooth-muscle relaxation, and cytokine regulation, making it a valuable tool for neuroendocrine, immunological, and cardiopulmonarystudies.

This high-purity lyophilized peptide provides a stable and consistent reagent for in vitro and in vivo studies examining G-protein-coupled receptor activity, anti-inflammatory signaling, and vascular homeostasis.

Applications

• Receptor-binding and signaling pathway investigations (VPAC1/VPAC2).

• Studies of vasodilation, smooth-muscle physiology, and airway function.

• Neuroimmune modulation and cytokine-regulation research.

• Analytical use as a reference peptide in pharmacological and biochemical assays.
