- 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 012-24 binds to exendin-4 when coated on ELISA wells and reacts specifically with exendin-4 in solution giving a Ka of 1.8x10E8 in an inhibition ELISA. The binding between ABS 012-24 and exendin-4 is disrupted by 0.1 M glycine pH 3.
By using the above monoclonal antibodies, it is possible to measure intact exendin-4 by a sandwich ELISA which is not subject to interference from GLP-1 or other glucagon-related peptides that may be present. ABS 033-10 is used as capture antibody in combination with a biotinylated detection antibody from the ABS 012 series. The best sensitivity in an unoptimized buffer assay was obtained with biotinylated ABS 012-35 as the detection antibody.
