VIP

A 28-amino-acid signaling peptide examined in laboratory signaling research.

VIP, or Vasoactive Intestinal Peptide, is a 28-amino-acid neuropeptide that is broadly distributed in mammalian tissues and belongs to the secretin/glucagon peptide superfamily. In the published literature it appears predominantly in cellular-signaling and neuropeptide research. Describing it as "studied in" these areas indicates where scientific attention has been directed, not a claim of any result. This page is background about the molecule as a research material and is not medical guidance or intended for human use.

Classification and structure

VIP is classified as a signaling neuropeptide. It is a 28-residue member of the secretin/glucagon peptide family and interacts with class B G-protein-coupled receptors that have been the subject of receptor-pharmacology research. It is handled in the laboratory as a defined peptide research compound.

Areas of research

VIP appears across several defined areas of the research literature.

• Receptor signaling — Investigated in research examining class B GPCR signaling in vitro.
• Neuropeptide research — Appears in the literature on neuropeptide distribution and function in model systems.
• Immunological signaling — Has been the subject of research examining immune-cell signaling pathways.

As always in this library, describing a compound as “studied in” an area is a statement about where scientific attention has gone — not a claim that it produces any result in humans or animals.

Handling and verification

Store lyophilized material cold and protected from light and moisture, following standard peptide-handling practice. Every in-stock lot ships with a verifiable third-party certificate of analysis (COA) documenting identity and purity.
