VIP is a vasoactive neuropeptide supplied by Apex Laboratory as a high-purity research peptide intended strictly for in-vitro laboratory research and development applications.
Compound Overview
Vasoactive Intestinal Peptide (VIP) is a 28-amino acid neuropeptide that activates VPAC1 and VPAC2 receptors (class B GPCRs). It plays roles in vasodilation, smooth muscle relaxation, neuromodulation, circadian rhythm regulation, and immune signaling. Research examines its broad-spectrum effects across multiple organ systems.
Research Background & Published Literature
Discovered in 1970 by Said and Mutt. Thousands of published studies in Journal of Neuroimmunology, Endocrinology, and Peptides. VIP is a key research tool in neuroendocrine, gastrointestinal, and immunological signaling studies.

Storage, Handling & Stability Guidelines
Store lyophilized material at -20°C for long-term stability. After reconstitution with sterile diluent, refrigerate at 2–8°C and minimize freeze-thaw cycles by aliquoting working volumes according to your standard operating procedures.
- Minimize time at ambient temperature during handling to preserve compound integrity.
- Avoid moisture exposure by resealing vials promptly after each withdrawal.
- Use appropriate personal protective equipment and follow your institution’s chemical safety protocols at all times.
- Label all aliquots with the compound name, concentration, date of reconstitution, and operator initials for complete traceability.
Quality Assurance & Analytical Verification
Apex Laboratory applies a dual-verification quality protocol to every batch before it enters inventory. Each lot undergoes High-Performance Liquid Chromatography (HPLC) to confirm chromatographic purity and Mass Spectrometry (MS) to verify molecular identity and molecular weight. This two-step analytical process ensures that the material you receive meets our ≥99% purity standard with confirmed molecular integrity. Certificates of Analysis documenting these results are available in the batch verification panel on this page and in the COA library for your internal quality records.
