Use of Somatostatin-28 trifluoroacetate salt

Somatostatin-28 (sheep) is a biologically active polypeptide, synthesised in the proximal intestinal epithelial cells. Somatostatin-28 (sheep) suppresses glucose-stimulated insulin secretion without affecting circulating basal insulin concentration. Somatostatin-28 (sheep) also targets to somatostatin receptor subtype 5 (SSTR5) to regulate GLP-1 secretion[1][2].
