Research Overview

Secretin

Secretin is a classic GI hormone with extensive physiology literature and established diagnostic use. It remains important for studying pancreatic secretory function, biliary responses, and duodenal feedback.

hGHRH(1-37)OH

Human GHRF(1-37)OH has appeared in studies examining how loss of C-terminal residues affects biological activity at the GHRH receptor. It is often used alongside other fragments to define structure-activity relationships within the GHRH family.
