VIP Research Peptide
Product Overview
Vasoactive Intestinal Peptide (VIP) is a naturally occurring peptide composed of 28 amino acids that has been extensively investigated in laboratory research involving neurobiology, cellular signaling, immune communication, and vascular physiology. Due to its widespread distribution throughout the nervous system and peripheral tissues, VIP remains an important subject of scientific investigation across multiple fields of biological research.
Northwest Peptides supplies VIP as a premium-quality lyophilized research peptide available in 5mg and 10mg laboratory formulations. Every production batch undergoes rigorous analytical verification and includes a batch-specific Certificate of Analysis (COA).
Research Overview
VIP has been widely studied for its interactions with VPAC1 and VPAC2 receptors and its role in cellular communication throughout numerous biological systems. Published laboratory research has investigated VIP in neurobiology, immune signaling, smooth muscle physiology, vascular regulation, and gastrointestinal research models.
Researchers continue to investigate VIP’s involvement in intracellular signaling pathways, inflammatory signaling, circadian biology, and peptide-mediated cellular communication. Ongoing laboratory studies seek to better understand its complex receptor interactions and biological mechanisms under controlled experimental conditions.
Scientific literature has also explored VIP in laboratory models involving respiratory biology, neuroimmune communication, metabolic regulation, and cellular homeostasis. These investigations remain focused on understanding biological function rather than establishing therapeutic outcomes.
