Vasoactive Intestinal Peptide (VIP), Human

VIP is a 28-residue amidated neuropeptide that activates VPAC1 and VPAC2 receptors. It regulates smooth-muscle relaxation, vasodilation, intestinal secretion, circadian signaling and immune responses.

• cardiovascular and renal signaling
• natriuretic peptide receptor research
• GPCR or cyclic-GMP signaling
• vascular and smooth-muscle studies

Disulfide connectivity, amidation and exact peptide length define these vasoactive reagents. Maintain sequence- and modification-matched controls for receptor and signaling comparisons.
