Description

Product Detail

1. Basic Information

Product Name: VIP Peptide (Vasoactive Intestinal Peptide)

Structure: 28-amino-acid endogenous regulatory neuropeptide

Molecular Weight: 3326.8 Da

Purity: ≥98%–99% (HPLC tested, research grade)

Appearance: White sterile lyophilized powder

VIP is a naturally derived human homologous bioactive peptide belonging to the secretin/glucagon superfamily. It features high biological safety, low rejection rate, stable activity, and complete in-vivo metabolism without accumulation or side effects.

2. Mechanism of Action

VIP Peptide exerts comprehensive biological regulation by binding to VPAC1 and VPAC2 G-protein-coupled receptors widely distributed in nerves, vascular endothelium, immune cells, and visceral organs.

It inhibits the NF-κB inflammatory signaling pathway, reduces the release of pro-inflammatory factors, and suppresses chronic low-grade inflammation throughout the body. Meanwhile, it protects endothelial cells and nerve cells from oxidative damage, stabilizes cell membrane activity, and repairs micro-damages caused by aging and oxidative stress.

In addition, VIP relaxes vascular smooth muscle, enhances endothelium-dependent vasodilation, improves blood flow efficiency, and realizes dual regulation of neuroimmune balance and vascular microcirculation.

3. Core Biological Functions

Vascular and Microcirculation Protection VIP optimizes vascular tension, improves systemic peripheral and visceral microcirculation, repairs damaged vascular endothelium, and delays vascular aging. It effectively maintains cardiovascular and cerebrovascular microcirculation stability.

Neuroprotection and Neural Regulation It stabilizes autonomic nerve excitability, relieves nerve fatigue and stress response, regulates circadian rhythm, and improves sleep quality and overall mental state. It protects both central and peripheral neural functions.

Immune Balance and Anti-Inflammation As a key neuroimmune messenger, VIP modulates immune tolerance, inhibits excessive immune response, and continuously improves chronic inflammatory conditions. It enhances systemic immune stability and endogenous defense capability.

Gastrointestinal Mucosal Protection and Metabolic Regulation VIP protects and repairs the gastrointestinal mucosal barrier, regulates intestinal peristalsis and secretion balance, improves digestive tract health, and stabilizes internal metabolic homeostasis.

4. Reconstitution and Concentration Specification

10 mg VIP lyophilized powder reconstituted with 5 mL BAC water

Final Concentration: 2 mg/mL

Note: Each 1 mL of reconstituted solution contains 2 mg of active VIP polypeptide.

5. Safety Profile

VIP is an endogenous bioactive peptide with excellent biocompatibility and safety. It has no systemic toxicity, no local irritation, and no drug dependence. After functioning in the body, it is completely decomposed into free amino acids without tissue accumulation, supporting long-term and stable use.

6. Storage Instructions

Sealed lyophilized powder should be stored at -20°C, away from light and moisture. Reconstituted solution must be stored at 2–8°C and used within 7 days to maintain optimal biological activity.

7. Disclaimer

VIP Peptide is a research-grade experimental peptide for laboratory research and technical reference only. It is not a pharmaceutical product and shall not be used for medical diagnosis, treatment or clinical medication purposes.
