Glucagon-like peptide-1 (GLP-1) is a 30-amino acid gut hormone secreted from the intestinal L-cells. The GLP-1 sequence is highly conserved among mammals and is released in its active form (7-36) in response to food intake. It is quickly degraded into its inactive form (9-36) after selective cleavage by dipeptidyl peptidase-4 (DPP-4). GLP-1 reduces glucose levels by regulating pancreatic secretion, slowing gastric emptying and lowering the desire for food intake. Therefore, it is an important biomarker for the study of diabetes and obesity.1-5 This kit is designed to measures total of GLP-1.
