(Cys(Et)2·7)-alpha-CGRP (human) is a modified calcitonin gene-related peptide (CGRP) with ethylated cysteine residues at positions 2 and 7, enhancing the peptide's stability and reducing disulfide bond formation. The modifications allow for more robust structural studies of CGRP in vasodilation and pain pathways. Researchers use this analog to explore CGRP receptor interactions and its role in neurogenic inflammation.
