VIP (Vasoactive Intestinal Peptide): Research Profile

VIP (vasoactive intestinal peptide) is a 28-amino-acid neuropeptide of the secretin/glucagon peptide superfamily. It is a well-characterized reference compound in neuroimmunology and receptor-signaling research.

Research background

VIP acts on VPAC receptors and is studied across preclinical contexts ranging from vasodilation and smooth-muscle signaling to circadian and immune research.

Reported activity in research models

In laboratory models, VIP has been investigated for immunomodulatory and anti-inflammatory signaling, circadian-rhythm regulation, and neuroprotection research. These observations are limited to laboratory and preclinical research settings and are not statements about outcomes in humans.

Handling and storage

Supplied as a lyophilized powder. Store lyophilized material at -20°C. Reconstitution with bacteriostatic or sterile water is common for laboratory handling; keep any reconstituted solution refrigerated and use it within the timeframe appropriate to the researcher’s protocol.

Analytical and COA

Purity is determined by HPLC and identity is confirmed by mass spectrometry. Each batch ships with a batch-specific certificate of analysis from an independent third-party laboratory; refer to the COA for lot-specific measured values. Endotoxin and sterility testing are not performed unless explicitly stated.
