Glucagon-like peptide 1 (GLP-1) is a peptide hormone produced by proglucagon. As an incretin hormone, GLP-1 can promote insulin secretion and inhibit glucagon secretion. GLP-1 has been used in the treatment of type 2 diabetes mellitus due to its effective hypoglycemic effect. GLP-1 is closely related to glycometabolism in the body and can be used as a biomarker for diseases related to glucose metabolism such as diabetes mellitus. Creative BioMart Biomarker offers sensitive testing service both for total GLP-1 and the biologically active forms of GLP-1, ensuring providing accurate and reliable test results.
