Human GLP-1 active ELISA kit is a reliable quantitative procedure for measuring active glucagon-like peptide-1 (GLP-1 active), this includes GLP-1 (7-36) amide and GLP-1 (7-37) specifically in human plasma (EDTA). This assay has a minimum sensitivity limit of 0.1 pmol/l.
Glucagon-like peptide-1 (GLP-1) is a neuropeptide that has an important role in regulating glucose homeostasis and is secreted in response to food intake. It belongs to the incretins family of gastrointestinal hormones that have the ability to increase the levels of insulin that is released from the beta cells of the islets of Langerhans after food intake. Glucagon-like peptide-1 also is able to inhibit glucagon release from the alpha cells of the islets of Langerhans. This causes a reduction in the rate of nutrients into the blood stream as a result of slowing gastric emptying, it is thought this may be directly leading to a reduction in food intake.
One of the major source for active glucagon-like peptide-1 in the periphery is the intestinal L cell that that have the ability to secrete GLP-1 as a gut hormone, on the other hand the major source in the brain is the nucleus of the solitary tract and this is known to be a source of a widely distributed set of GLP-1 projection neurons. There are multiple forms of human GLP-1 active that exist and the biologically active forms include GLP-1 (7-37) and GLP-1 (7-36) NH2. These can be formed as a result of selective cleavage of the pro-glucagon molecule.
