Description
Product Overview
Vasoactive Intestinal Peptide (VIP) is a premium-quality synthetic 28-amino acid neuropeptide manufactured exclusively for laboratory and scientific research. Naturally produced throughout the gastrointestinal tract, central nervous system, and immune system, VIP functions as an important biological signaling molecule involved in numerous physiological processes.
Extensive research has demonstrated that Vasoactive Intestinal Peptide (VIP) regulates inflammatory signaling, promotes vascular relaxation, maintains epithelial barrier integrity, influences neurotransmission, and contributes to circadian rhythm regulation. These diverse biological activities make VIP an essential research peptide across immunology, neuroscience, pulmonary medicine, gastrointestinal biology, and cardiovascular research.
Manufactured using advanced Solid-Phase Peptide Synthesis (SPPS), each production batch undergoes stringent purification by High-Performance Liquid Chromatography (HPLC) and verification through Mass Spectrometry (MS) to ensure exceptional purity, identity, and batch-to-batch consistency.
Peptide Overview
Vasoactive Intestinal Peptide belongs to the glucagon-secretin peptide family and functions primarily as a non-adrenergic, non-cholinergic neurotransmitter.
Its biological effects are mediated through activation of two G-protein coupled receptors:
• VPAC1
• VPAC2
Binding to these receptors stimulates adenylate cyclase activity, increasing intracellular cyclic adenosine monophosphate (cAMP). This signaling pathway regulates numerous biological functions, including:
• Immune cell communication
• Smooth muscle relaxation
• Vasodilation
• Mucosal protection
• Neurotransmission
• Hormonal regulation
• Circadian rhythm signaling
Because of its broad physiological activity, VIP continues to receive considerable attention in translational biomedical research.

Handling & Reconstitution
For optimal stability:
1. Briefly centrifuge the vial before opening.
2. Reconstitute using sterile deionized water or phosphate-buffered saline (PBS).
3. If necessary, use a minimal amount of sterile 1% acetic acid to improve solubility.
4. Gently swirl until completely dissolved.
5. Avoid vigorous vortexing or repeated agitation.
Following reconstitution, prepare single-use aliquots whenever possible to minimize degradation caused by repeated freeze-thaw cycles.
Storage Recommendations
Lyophilized Powder
Store at -20°C in a dry, light-protected environment. Under proper storage conditions, the peptide remains stable for up to 24 months.
Reconstituted Solution
Store at 2–8°C if used within seven days.
For extended preservation, divide into aliquots and store at -80°C. Avoid repeated freeze-thaw cycles to maintain peptide integrity.
