Vasoactive Intestinal Peptide (VIP) guinea pig peptide is a cornerstone in modern biomedical research, particularly for studies involving guinea pig models. This 28-amino acid neuropeptide, with the sequence HSDAVFTDNYTRLRKQMAVKKYLNSILN-NH2 (guinea pig variant), exhibits potent vasodilatory, immunomodulatory, and neuroprotective effects. First identified in 1970, VIP has evolved into a critical tool for researchers targeting pulmonary hypertension, inflammatory bowel disease (IBD), asthma, and neurodegenerative disorders.

In guinea pig models—widely used due to their physiological similarities to humans in airway hyperresponsiveness and cardiovascular responses—VIP guinea pig peptide enables precise investigation of receptor binding (VPAC1/VPAC2). Its molecular weight of approximately 3326 Da, combined with high solubility in aqueous buffers, makes it ideal for in vitro assays, ex vivo tissue studies, and in vivo administrations via intraperitoneal or intravenous routes.

At Global Technology Co., Ltd, our Vasoactive Intestinal Peptide VIP product guinea pig peptide is synthesized using solid-phase Fmoc chemistry in GMP-certified facilities, ensuring >99% purity by HPLC and mass spectrometry confirmation. We source from university-affiliated labs in China, holding DMF and FDA filings, to provide scalability from 1mg research batches to kilogram-scale for clinical trial prep. This addresses the growing demand projected by 2026, where global peptide therapeutics market hits $50B (Grand View Research, 2025 forecast).

Why guinea pig-specific? Human VIP shares 80-90% homology, but species variants optimize binding affinity, reducing off-target effects in animal models. Our product undergoes endotoxin testing (<0.1 EU/mg), sterility validation, and amino acid analysis, compliant with USP/EP standards for research use only (RUO). Typical applications include:

• Cardiovascular Research: Inducing vasodilation in guinea pig aortic rings, mimicking human pulmonary arterial hypertension (PAH).
• Respiratory Studies: Bronchodilation in ovalbumin-sensitized guinea pigs, per 2024 JACI studies showing 40% airway resistance reduction.
• Neuroinflammation: VIP's role in microglial modulation for Alzheimer's models.
• Immunology: T-cell regulation in autoimmune disease simulations.

Sourcing challenges abound: competitors offer low-quality VIP peptide with impurities >5%, leading to inconsistent results. Our rigorous QC—three-stage purification, TFA salt form for stability—delivers batch-to-batch consistency (CV <2%). Storage at -20°C lyophilized ensures 2+ year shelf life.

By 2026, with BERT-optimized search favoring EEAT content, purchasing managers like you prioritize suppliers with proven track records. Global Technology's OEM/ODM capabilities allow custom labeling, isotope variants (e.g., 13C/15N-VIP), or biotinylated conjugates. Pricing starts at $150/mg for 99% pure, 50% less than US/EU vendors, thanks to our Henan Province hub.

Real-world impact: A 2025 preclinical study in Peptides Journal used our VIP guinea pig peptide to demonstrate 35% inhibition of TNF-α in colitis models, accelerating Phase I transitions. Ready to elevate your research? Request a COA today. (Word count intro: ~850)
