VIP (Vasoactive Intestinal Peptide) is a 28-amino-acid neuropeptide widely distributed in the nervous and digestive systems, studied in neuroscience and immune-regulation research. It is supplied as a high-purity white lyophilized powder, >=99% by HPLC, in sealed vials for laboratory use. VIP is investigated in research on neuropeptide signaling, inflammation modulation, autonomic regulation and gut-brain communication, and is commonly applied in cell-based and preclinical studies. The lyophilized format ensures high stability and easy reconstitution for reproducible experimental dosing. Strict quality control is maintained on every batch, and COA is available for specific batches on request. Keep the unopened product sealed at 2-8 degree C away from light; -20 degree C is recommended for long-term storage. Small and bulk orders are both welcome, and OEM and discreet neutral packing are offered. VIP is studied in receptor pharmacology and inflammation models where its protective effects are measured by cytokine and tissue endpoints, and investigators value its defined 28-residue sequence for reproducible dosing across receptor-binding and functional assays. The lyophilized material reconstitutes in buffer, and our records verify purity. Trial and bulk quantities are available, with storage and international delivery support. VIP is released with batch documentation, and the lyophilized 28-mer reconstitutes cleanly for receptor and inflammation assays. We can bundle it with related peptides in one order for receptor panels, and match packing to whether the destination route needs cold-chain handling. With a stable supply chain and strict quality control, we serve research teams and distributors in many countries. Every parcel is professionally packed and tracked, and we provide timely communication from order to delivery, plus after-sales support.
