Used in research and development for neurological and migraine-related conditions. Targets PACAP-38, a peptide involved in vasodilation and pain signaling, making it valuable for studying migraine pathophysiology. Enables quantification and neutralization of PACAP-38 in biological samples, supporting drug discovery and biomarker validation. Employed in preclinical studies to assess target engagement and mechanism of action for anti-migraine therapeutics. Also utilized in immunoassays to measure PACAP levels in response to treatment.
