生物活性

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

IC50 & Target[2]

SSTR5

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
