Product Overview

VIP is a 28-amino acid neuropeptide and potent endogenous anti-inflammatory mediator. Signals via VPAC1/VPAC2 receptors across neuroimmune, airway, circadian, and gastrointestinal research domains.

Research Applications

  • 28-amino acid neuropeptide — secretin/glucagon superfamily
  • VPAC1/VPAC2 signaling: cAMP/PKA/CREB cascade
  • Potent endogenous anti-inflammatory (suppresses TNF-α, IL-6, IL-12)
  • Promotes Treg differentiation and mucosal tolerance
  • VPAC2 essential for circadian pacemaker function in SCN

Key Features

  • Validated by VIP-KO and VPAC-KO animal models
  • ≥99% purity confirmed by RP-HPLC and ESI-MS
  • For laboratory research use only
