The protein encoded by this gene is actually a preproprotein that is cleaved into four distinct mature peptides. One of these, glucagon, is a pancreatic hormone that counteracts the glucose-lowering action of insulin by stimulating glycogenolysis and gluconeogenesis. Glucagon is a ligand for a specific G-protein linked receptor whose signalling pathway controls cell proliferation. Two of the other peptides are secreted from gut endocrine cells and promote nutrient absorption through distinct mechanisms. Finally, the fourth peptide is similar to glicentin, an active enteroglucagon. [provided by RefSeq, Jul 2008]

This uses GTX60951 as capture antibody in combination with biotinylated detection antibody GTX60955- 02 to measure the sum of GLP-1(7-36)amide, GLP-1(1-36)amide and GLP-1(9-36)amide in biological samples. Relative to measuring the two active forms of GLP-1, the responses are reduced by not measuring the contribution of GLP-1(7- 37) to the overall response, but this is compensated for by measuring an approximately equal contribution from GLP-1(1-36)amide. However, the GLP-1(9-36)amide degradation product is also measured, augmenting the response above that of the active forms alone. This assay cannot detect changes in active GLP-1 in response to treatment with DPP-4 inhibitors, and is therefore only suitable for experiments in which changes in GLP-1 degradation are irrelevant.

GTX60951 ELISA Image
This uses GTX60951 as capture antibody in combination with biotinylated detection antibody GTX60952 -02 exclusively to measure GLP-1(7-36)amide in biological samples. GLP-1(7-36)amide is the principal active form of the peptide, and has been estimated to make up about 70% of the physiological response. Relative to measuring both active forms of GLP-1 together, the responses are reduced by not measuring the approximately 30% contribution of GLP-1(7-37) to the overall response. There is no cross-reactivity with any extended or truncated physiological form of GLP-1(7-36)amide. Specimens must be collected into tubes containing an adequate amount of DPP-4 inhibitor (in addition to routine peptidase inhibitors) to prevent the rapid in vitro degradation of the active peptide.
