Vasoactive Intestinal Peptide · 28-Amino Acid Neuropeptide
28-amino acid neuropeptide with vasodilatory and immunomodulatory properties. Studied in pulmonary hypertension, MCAS, and inflammatory pathway research.
Vasoactive Intestinal Peptide (VIP) is a 28-amino acid neuropeptide found throughout the nervous system and immune tissues. Research documents potent vasodilation via VPAC1/VPAC2 receptor activation, bronchodilation, and anti-inflammatory immune modulation. Clinical research interest spans pulmonary arterial hypertension, MCAS (mast cell activation syndrome), and inflammatory bowel disease.
Store lyophilized at -20°C. Reconstitute in sterile saline. Very short half-life (~1 min IV) — research protocols use bolus or infusion models.
