Used to measure glucagon-like peptide 1 (GLP-1) levels in mouse samples such as serum, plasma, or cell culture supernatants. Commonly applied in diabetes and metabolism research to evaluate insulin secretion regulation, gut hormone function, and the effects of therapeutic interventions. Supports studies on obesity, glucose homeostasis, and gastrointestinal physiology by providing a reliable and sensitive method for quantifying active and total GLP-1 in preclinical models.
