High Purity VIP CAS 40077-57-4 5mg 10mg per Vial for Cardiovascular and Neurological Research

High Purity VIP CAS 40077-57-4 5mg 10mg per Vial for Cardiovascular and Neurological Research

VIP (Vasoactive Intestinal Peptide) is a 28-amino acid neuropeptide belonging to the glucagon/secretin superfamily. It functions as both a neurotransmitter and a neuroendocrine hormone. VIP is widely distributed in the central and peripheral nervous systems, as well as in various peripheral organs including the gastrointestinal tract, cardiovascular system, and reproductive tissues. This product is supplied as a sterile white to off-white lyophilized powder in sealed vials, ensuring high stability and bioactivity for research purposes only.

VIP acts primarily through binding to G protein-coupled receptors VPAC1, VPAC2, and PAC1. It plays a key role in mediating smooth muscle relaxation, vasodilation, neurotransmission, and immunomodulation. The lyophilized formulation preserves the peptide's structural integrity and bioactivity, allowing for consistent and reproducible results in controlled laboratory settings. Each vial is hermetically sealed to prevent moisture absorption and contamination. The product is intended for in vitro and in vivo research applications, including cell culture studies, animal model experiments, receptor binding assays, and biochemical analyses.

Note: For laboratory research use only. Not for human consumption, medical treatment, therapeutic injection, or veterinary application.
