VIP — Vasoactive Intestinal Peptide

VIP (Vasoactive Intestinal Peptide) is a synthetic 28-amino-acid peptide supplied in lyophilized form for controlled laboratory, analytical, and scientific research. The human, porcine, and rat VIP sequence is highly conserved and is commonly investigated in laboratory studies involving peptide characterization, receptor interactions, molecular signaling, stability, and structure–activity relationships.

Sigma-Aldrich lists synthetic VIP under CAS 40077-57-4, with an empirical formula of C147H238N44O42S and a molecular weight of 3325.80 g/mol.

About VIP

Vasoactive Intestinal Peptide is a naturally occurring 28-residue peptide that is also produced synthetically for research applications. Its defined amino-acid sequence and molecular structure make it suitable for laboratory studies involving peptide–receptor interaction, analytical identification, molecular signaling, peptide stability, and biochemical characterization.

A commonly referenced VIP sequence is:

His–Ser–Asp–Ala–Val–Phe–Thr–Asp–Asn–Tyr–Thr–Arg–Leu–Arg–Lys–Gln–Met–Ala–Val–Lys–Lys–Tyr–Leu–Asn–Ser–Ile–Leu–Asn. PubChem lists the corresponding 28-residue VIP sequence in its scientific record.

One detail to keep correct on the AVM page: scientific databases can represent VIP under different salt/protonation or reference forms, which may produce slightly different formula, molecular-weight, or CAS listings. For the product you actually sell, the batch-specific COA should be the final reference for identity and analytical characteristics.

Research Status

VIP is widely used as a biochemical and peptide research material. Its use as a laboratory reagent does not by itself establish any therapeutic indication for the material supplied by AVM Labs USA.

AVM Labs USA Research Standard

AVM Labs USA supplies VIP 5 mg exclusively for laboratory, analytical, and scientific research purposes. Researchers should consult the applicable batch-specific Certificate of Analysis when confirming identity, purity, and analytical characteristics.
