VIP (vasoactive intestinal peptide) is a 28-amino-acid neuropeptide with broad anti-inflammatory, vasodilatory and neuroprotective actions mediated through VPAC1 and VPAC2 receptors. Its pleiotropic signaling makes it a central tool in neuroimmunology and gastrointestinal research. For many groups, this 28-mer enters the workflow because its broad receptor activity opens several research angles at once, and investigators use it when they want a defined neuropeptide reference with reproducible pharmacology. Researchers tend to reach for it in anti-inflammatory and vasodilatory studies where receptor-subtype mapping matters. The value comes down to having a complete, intact sequence rather than a fragmented analog. We deliver it with HPLC-verified purity and can bundle related receptor peptides in one order, with the lot record included so every binding panel cites the same source. When you order this 28-mer, the parcel arrives with the purity report and reconstitution notes, and related receptor peptides can be bundled in the same shipment. Binding panels can hold one lot for the whole study, with packing matched to the destination. Trial and bulk sizes are both available. All products are manufactured under controlled conditions and released only after purity verification. We welcome small and large orders alike, provide professional packing and fast worldwide dispatch, and offer steady supply to research institutions, labs and trading partners.
