Secretin (28–54), human TFA(CAT: I046029) is a synthetic C-terminal fragment of the human secretin peptide hormone, supplied as a trifluoroacetate (TFA) salt. Secretin is a member of the glucagon–vasoactive intestinal peptide (VIP) family and plays key roles in regulating pancreatic bicarbonate secretion, gastric acid inhibition, and intestinal motility. The (28–54) fragment retains important biological activity, making it a useful tool for probing receptor binding, signaling mechanisms, and peptide structure–function relationships. Secretin (28–54), human TFA, is widely applied in gastrointestinal physiology, neuroendocrinology, and receptor pharmacology research to explore peptide hormone interactions and therapeutic peptide development.
