α-CGRP (mouse, rat) TFA
Based on 8 publication(s) in Google Scholar
α-CGRP (mouse, rat) TFA, a neuropeptide (calcitonin gene-related peptide (CGRP)) mainly expressed in neuromuscular junction, is a potent vasodilator. α-CGRP (mouse, rat) TFA can lead to a fall in blood pressure and an increase in heart rate by peripheral administration, also relax colonie smooth muscle. α-CGRP (mouse, rat) TFA has the potential in cardiovascular, pro-inflammatory, migraine and metabolic studies.
