CGRP (rat) TFA (CAS No 83651-90-5) is used in biomedical research particularly in the study of neuropeptides involved in pain and vasodilation pathways Originating from rat calcitonin gene-related peptide it interacts primarily with the CGRP receptor playing a role in the transmission of pain and regulation of vascular tone In vitro activities are typically observable in the nanomolar to low micromolar range making it suitable for mechanistic studies in cell-based assays and functional experiments This compound is widely applied in cell models to investigate neuronal signaling and is also used in animal studies to understand migraine pathophysiology and vasodilation mechanisms Additionally it serves as a tool in drug screening particularly for the development of migraine therapeutics Experimental concentrations typically depend on the specific research design
