Peptide Structure & Amino Acid Sequence

VIP is a 28-amino acid linear neuropeptide belonging to the secretin/glucagon superfamily of peptides. Its full sequence — 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 — encodes a broad range of receptor-binding capacities, most notably at VPAC1 and VPAC2 G-protein coupled receptors. This sequence is highly conserved across mammalian species, making it particularly relevant for translational research models. The peptide’s C-terminal amidation is a critical structural feature that contributes to receptor affinity and biological stability in experimental settings.

Purity & Analytical Verification (HPLC & MS)

Every VIP Peptide Vial supplied by Direct Anti Peptide is analytically verified to a minimum purity of ≥98% using reverse-phase High-Performance Liquid Chromatography (HPLC). Mass spectrometry (MS) confirmation is performed to validate the molecular weight and confirm the correct primary sequence, ensuring that researchers receive a product free from truncated sequences, racemized residues, or synthesis-related impurities. Certificates of Analysis (CoA) are available upon request, providing full traceability for laboratory documentation and institutional compliance purposes.

Quality Control & Lyophilization Integrity

The lyophilization process used in the production of this research peptide is conducted under controlled freeze-drying parameters to preserve bioactivity and structural integrity over extended storage periods. Lyophilized peptides exhibit superior shelf stability compared to solution-phase alternatives, reducing degradation risk during transit and storage. Each vial is sealed under inert conditions to prevent moisture ingress and oxidative degradation. Batch-to-batch consistency is maintained through standardized synthesis and QC protocols, ensuring reproducibility across research experiments.

Safety, Handling & Laboratory Precautions

This product is intended exclusively for use by trained laboratory professionals operating within a regulated research environment. Standard laboratory safety protocols must be observed at all times when handling this peptide reagent. Appropriate personal protective equipment (PPE), including gloves, lab coat, and eye protection, should be worn. This compound must not be administered to humans or animals under any circumstances. Dispose of all materials in accordance with applicable institutional and regulatory waste management guidelines.

Reconstitution, Packaging & Storage

The VIP Peptide Vial arrives in lyophilized powder form, sealed in a borosilicate glass vial with a crimp-top closure to maintain sterility during shipping and storage. For laboratory reconstitution, researchers should refer to their institution’s standard operating procedures for peptide preparation in aqueous or buffered solutions. Once reconstituted, aliquot immediately and store at −80°C to minimize freeze-thaw degradation. Avoid repeated freeze-thaw cycles. Keep away from direct light and moisture. Proper storage conditions are essential to preserving the functional integrity of the peptide for downstream research applications.

Intended Research Use & Market Positioning
