Overview
VIP — Vasoactive intestinal peptide
What is VIP?
VIP — vasoactive intestinal peptide — is an endogenous 28-residue neuropeptide found throughout the gut, brain, and immune system. Few signalling peptides have a research literature this broad: immune modulation, pulmonary biology, circadian signalling, and smooth-muscle work all lean on it.
Why researchers choose it
As a native human sequence with well-mapped receptors (VPAC1/VPAC2), VIP is a foundational reference peptide: protocols use it to anchor receptor studies and as the benchmark against which analogs are compared. Synthetic supply matters because the native peptide degrades quickly and is impractical to isolate. REPRIME supplies a lyophilized 10 mg vial, reconstituted on the researcher's schedule.
The REPRIME standard
A reference peptide is only as good as its reference data. Every batch is independently HPLC-tested and released at ≥99% main-peak purity, with the batch COA published in the Certificates repository. The 10 mg lyophilized vial ships cold-chain in tamper-evident packaging with a unique REP-XXXX-XXXX-X code — one scan at first use confirms it is genuine. For laboratory and research use only; not for human consumption.
Storage
