Discontinued ProductUnfortunately Cortistatin-8 (Cat. No. 3033) has been withdrawn from sale for commercial reasons.
Synthetic cortistatin analog that lacks the ability to bind somatostatin receptors but retains ghrelin receptor binding. Acts as a ghrelin receptor antagonist; counteracts the response of ghrelin on gastric acid secretion.
(Modifications: Trp-4 = D-Trp, Disulfide bridge between 2 - 7, Lys-8 = C-terminal amide)
