VIP in research
VIP is a 28-residue neuropeptide used in receptor biology research around VPAC1, VPAC2, and PAC1-related signaling. Published lab work commonly measures cAMP response and receptor binding across cell-line systems.
Peptide identity and handling
The C-terminal amide and methionine-containing sequence are verified by lot identity data. Net peptide content is reported to support concentration-controlled receptor assay setup.
Storage and handling
Keep sealed lyophilized vials at -20 °C protected from light. Reconstitute into single-use aliquots and minimize time at room temperature after solubilization.
Documentation
CoA includes MS identity, HPLC purity, and net peptide content. Batch records are available by lot.

Storage and handling
Handle VIP as a lyophilized research reagent: cold, dry, light-protected storage; choose reconstitution buffer per your SOP; plan aliquots to limit freeze–thaw; and keep the lot CoA with the inventory record.
Research framing
Use VIP in published model-system terms only — receptor family, pathway context, assay controls, and concentration planning. Do not transfer assumptions from adjacent peptides without a documented comparison protocol. Research use only.
Documentation checklist
- Storage and stability records for the received lot
- Lot CoA with HPLC, MS identity, and net peptide content
- Literature and assay context filed with the protocol
- Verify lots in the CoA Library
Product FAQ
Is VIP intended for human or clinical use?
No. BluGen listings are research use only (RUO) for qualified laboratory programs — not clinical, diagnostic, therapeutic, veterinary, food, drug, or cosmetic use.
What documentation ships with VIP?
Each lot includes a certificate of analysis with HPLC purity, MS identity confirmation, and net peptide content. Verify lots in the CoA Library.
Where can I verify the current-lot CoA for VIP?
Search by compound or lot number in the CoA Library: https://getblugen.com/coa-library/
What sequence is listed for VIP?
The listed 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-NH2. Confirm against the lot-specific CoA before release into inventory.
How should lyophilized VIP be stored?
Store sealed vials cold, dry, and protected from light per the lot CoA and your institutional SOP. Aliquot reconstituted stock to limit freeze-thaw cycles.
Can institutions request a quote for VIP?
Yes. Academic labs and CROs can request quotes and NET-30 billing after vendor qualification via the contact/procurement desk.
