M617 TFA（Cat No.:I045808）is the trifluoroacetate salt of M617, a synthetic peptide analog designed as a potent and selective agonist of the cholecystokinin-2 (CCK2) receptor. By mimicking the activity of gastrin/CCK peptides, M617 stimulates receptor-mediated signaling involved in gastric acid secretion, gastrointestinal motility, and cellular growth pathways. Its high affinity and stability make it a valuable pharmacological tool for studying CCK2 receptor function in both physiological and pathological contexts. M617 TFA is particularly useful in research on digestive regulation, cancer biology, and receptor-targeted therapeutic development.
