Used in biomedical research to measure levels of glucagon-like peptide-1 (GLP-1) in rat samples. This assay helps in studying glucose metabolism, insulin regulation, and gut hormone responses. Commonly applied in diabetes and obesity research to evaluate the effects of drugs, diets, or genetic modifications on GLP-1 secretion. Enables high-throughput analysis of multiple samples with high sensitivity and specificity. Supports investigation of gastrointestinal and endocrine system functions in preclinical animal models.
