Overview

Description

VIP (Vasoactive Intestinal Peptide) is a high-purity (≥99%) 28-amino acid neuropeptide with a molecular weight of 3326.8 Da. This regulatory peptide is studied in neuroendocrine, gastrointestinal, and immune function research. Supplied as a lyophilized powder, store at -20°C protected from light and moisture. Used for examining vasodilation, circadian rhythms, and neurotransmitter pathways.

Mechanism of Action

Vasoactive intestinal peptide (VIP) signals primarily through the GPCRs VPAC1 and VPAC2; a third receptor, PAC1, is shared with PACAP but has substantially lower VIP affinity. VIP signaling mediates vasodilation, anti-inflammatory action, and modulation of immune-cell trafficking (PMC3415633; PMC3883350).

Research Applications

  • VPAC1/VPAC2 receptor pharmacology (PMC3415633)
  • Immune-cell trafficking and cytokine modulation models (PMC3883350)
  • GI motility and secretion regulation studies (PMC6743256)

FAQ

Frequently Asked Questions

What is VIP?

VIP is a research compound supplied for in-vitro laboratory use. Also known as Vasoactive Intestinal Peptide. Sequence: 28 amino acid neuropeptide. Supplied for neuropeptides laboratory research. A third-party Certificate of Analysis is published for the current lot. Research Use Only — not for human or veterinary use.

What purity is VIP?

The current Certificate of Analysis for VIP reports 99.013% purity by HPLC (Accumark Labs report EUKK-2QL4).

Does VIP include a Certificate of Analysis?

Yes. Accumark Labs report EUKK-2QL4 for VIP is on our COA page, with a link to the lab's own report.

How should VIP be stored?

VIP is supplied as a lyophilized powder. Store it at −20°C or below, protected from light and moisture — lyophilized material is stable frozen. Once reconstituted, keep it refrigerated and avoid freeze-thaw cycles.

How is VIP shipped?

Orders ship at a $15 flat rate, free on orders of $200 or more, in discreet, insulated packaging. Domestic delivery takes 2–3 business days — 2-day across California, nearby Nevada, and on orders of $250+.

Can VIP be used on humans or animals?

No. VIP is supplied strictly for in-vitro laboratory research. It is not for human or veterinary use, consumption, or diagnostic or clinical applications.

Is VIP the same as Vasoactive Intestinal Peptide?

Yes. VIP is also spelled or referred to as Vasoactive Intestinal Peptide. These are naming variants of the same compound, not different products.

How do I verify the VIP Certificate of Analysis is real?

Open the lab report link on our certificate page — it goes to Accumark Labs's own verification portal, not a file we host, so the result can't be edited by us. Confirm the report ID (EUKK-2QL4) and figures match what's shown here.

What is the price per mg for VIP?

The 5mg size of VIP is $13.00 per mg. See the size selector above for per-mg pricing on every available size.
