Biological Activity

[Description]:

Xenin-8, a C-terminal octapeptide, is a biologically active fragment of Xenin. Xenin is a 25-amino acid peptide of the neurotensin/xenopsin family. Xenin-8 stimulates basal insulin secretion and potentiates the insulin response to glucose in a dose-dependent manner (EC50=0.16 nM)[1].

[In Vitro]

Xenin-8 augments Arginine-induced insulin release (by 40%) and potentiates the glucagon responses to both Arginine (by 60%), Carbachol (by 50%). Xenin-8 counteracts the inhibition of glucagon release induced by increasing the glucose concentration[1].
