Target
Exendin-4 is a 39 amino acid peptide found in venom from the Gila monster?Heloderma suspectum.?It is a member of the glucagon-secretin family of peptide hormones and neuropeptides. Exendin-4 is a potent agonist of the GLP-1 receptor and hence a potent stimulator of insulin secretion.
Application 1
ELISA
ABS 012-20 binds to exendin-4 when coated on ELISA wells and reacts specifically with exendin-4 in solution giving a Ka of 1.6x10E8 in inhibition ELISA. The binding between ABS 012-20 and exendin-4 is disrupted by 4.5 M MgCl2.?
