Buy VIP Peptide (Vasoactive Intestinal Peptide) Research Compound

Researchers looking to buy VIP peptide for laboratory study will find this naturally occurring 28-amino-acid neuropeptide is one of the most extensively researched neuropeptides in modern immunology, neurology, and vascular biology literature. VIP (Vasoactive Intestinal Peptide) was first isolated from the small intestine in 1970 and has since been identified throughout the central nervous system, peripheral nervous system, and immune tissues. The compound belongs to the secretin/glucagon peptide superfamily and is studied across an exceptionally broad range of biological systems — vascular, immune, neurological, gastrointestinal, and respiratory — making it a foundational reference compound in multiple research disciplines.

Mechanism of Action

Vasoactive Intestinal Peptide (VIP) has been investigated in published research for activity across several biological pathways, including:

  • VPAC1 and VPAC2 receptor agonism — binding to two distinct G-protein-coupled receptors with broad tissue distribution
  • cAMP signaling — activation of adenylate cyclase and downstream cAMP-mediated pathways
  • Vasodilation pathways — research on smooth muscle relaxation and vascular tone in preclinical models
  • Immune modulation — investigations into T-cell differentiation, macrophage polarization, and cytokine signaling
  • Anti-inflammatory signaling — research on pro-inflammatory cytokine suppression including TNF-α, IL-6, and IL-12
  • Neuroprotection — studies on neuronal survival and neurodegenerative pathway research models
  • Circadian rhythm regulation — research on suprachiasmatic nucleus function and biological-clock pathways
  • Bronchodilation and pulmonary research — investigations into airway smooth muscle and respiratory pathway models

This peptide – VIP – is unusual among neuropeptides in that it is studied across an exceptionally broad range of biological systems — vascular, immune, neurological, gastrointestinal, and respiratory — making it a foundational reference compound in multiple research disciplines.

Research Applications

Widely used in research contexts including:

  • Vasodilation and vascular tone research
  • Immune modulation and autoimmune research models
  • Anti-inflammatory pathway studies
  • Neuroprotection and neurodegenerative research
  • Sarcoidosis and chronic inflammatory research models
  • Mast cell activation syndrome (MCAS) research
  • Pulmonary and airway smooth muscle research
  • Circadian rhythm and suprachiasmatic nucleus studies
  • Comparative analysis alongside related peptides such as PACAP

Product Specifications

  • Compound: VIP (Vasoactive Intestinal Peptide)
  • Form: Lyophilized white powder
  • Purity: ≥99% (verified by HPLC and mass spectrometry)
  • Available sizes: 10mg
  • Third-party tested: Certificate of Analysis available on request

Reconstitution & Storage

Lyophilized VIP should be stored at -20°C for long-term stability and protected from light. Once reconstituted with bacteriostatic water, the solution should be refrigerated at 2–8°C and used within the timeframe indicated on the product COA. This peptide – VIP – is particularly sensitive to enzymatic degradation in solution, so careful handling and avoidance of repeated freeze-thaw cycles is important to preserve peptide integrity.

Shipping & Handling

All orders are shipped with temperature-controlled packaging to preserve peptide integrity. Domestic orders typically arrive within 2–4 business days. Tracking is provided on every order.

Storage & Handling

Storage & Handling

Proper storage and handling are essential to maintaining peptide stability and ensuring the integrity of your research material.

Storage Recommendations

Lyophilized peptides should be stored at -20°C for long-term preservation. For short-term storage of up to 30 days, refrigeration between 2-8°C is acceptable. Reconstituted peptides should always be refrigerated and used within 30 days.

Avoid the following:

Direct sunlight or UV exposure Repeated freeze-thaw cycles Temperature fluctuations Storage at room temperature beyond brief handling periods

Reconstitution Best Practices

Allow vials to reach room temperature before opening to prevent condensation. Use bacteriostatic water as the diluent for most peptides, injecting slowly along the side of the vial. Gently swirl to dissolve — do not shake. Allow the solution to fully dissolve before drawing for research use.

Shelf Life

Lyophilized peptides maintain potency for up to 24 months when stored properly at -20°C. Reconstituted solutions should be used within 30 days for optimal research results.
