GMP and ISO9001 Certified Factory Supply Vasoactive Intestinal Peptide VIP Freeze-Dried Powder 10mg Wholesale Vasoactive Intestinal Peptide Aviptadil Powder VIP CAS：40077-57-4
The core component of VIP peptide powder is vasoactive intestinal peptide (VIP), a neuro peptide composed of 28 amino acids with extensive physiological activities. It plays a pivotal role in vasodilation and immune regulation, and is widely distributed in organs such as the central nervous system, lungs, and gastrointestinal tract. By activating VPAC1/VPAC2 receptors, VIP effectively regulates multiple critical physiological processes, including cell proliferation, immune responses, and smooth muscle relaxation. To meet diverse research needs, we not only provide high-purity full-length VIP peptide powder but also offer various fragments and variants, including VIP (1-12), VIP (3-28), and VIP antagonists, ensuring comprehensive support for your research.

FAQ:
Q1: How can I use VIP peptide powder correctly?To maintain the activity of the peptide, we recommend that you:
Dissolve: Use sterile physiological saline or PBS buffer to dissolve the powder, and try to avoid repeated freezing and thawing.
Dosage reference: In cell experiments, the commonly used working concentration is 10 ⁻⁹ M to 10 ⁻⁷ M; when used in animal experiments, the optimal dose needs to be explored based on your specific research model.
Proper storage: Please freeze unused freeze-dried powder at -20 ℃; The dissolved solution is best packaged and frozen to avoid affecting its activity.
Q2: What special precautions should be taken during use?
Please pay attention to the following points in the experimental design:
Short half-life: VIP is metabolized rapidly in the body (about 2 minutes), and if effective concentration needs to be maintained, continuous administration or selection of more stable analogues may be considered.
Potential reactions: When using high doses, it is necessary to observe whether there is hypotension or facial flushing caused by vasodilation.
Clear purpose: This product is a research specific reagent and is strictly prohibited from being used on the human body.
Q3: How to determine the quality of VIP peptide powder?
Choosing high-quality products is the foundation of successful experiments. Please request the following key documents from the supplier:
Purity certificate: HPLC purity analysis report, purity higher than 95% is preferred.
Identity authentication: Mass spectrometry report to ensure the accuracy of amino acid sequence and molecular weight.
Safety indicators: Sterility and endotoxin testing reports, endotoxin content should be less than 1 EU/μ g.
