ELISA

ABS 012-35 binds to exendin-4 when coated on ELISA wells and reacts specifically with exendin-4 in solution giving a Ka of 1.1x10E9 in an inhibition ELISA. The binding between ABS 012-35 and exendin-4 is disrupted by 4.5 M MgCl2.ABS 012-35 (as biotinylated detection antibody) forms a sandwich ELISA pair with ABS 033-10 (as capture antibody) for measuring exendin-4, giving a detection limit of as little as 40 pmol/L in an unoptimized buffer assay.

Specificity
Specificity	Specific for exendin-4. No cross-reactivity with GLP-1, GLP-2 (human) or glucagon coated on ELISA wells.The epitope is in the 9-39 region of the peptide, and the antibody cross-reacts strongly with exendin (9-39) amide.
Immunogen	Synthetic exendin-4
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.
