Used for the quantitative measurement of Butyrylcholinesterase (BUT) activity in rat biological samples such as serum, plasma, or tissue homogenates. This ELISA kit enables researchers to assess liver function, monitor metabolic disorders, and evaluate neurotoxicity or organophosphate exposure in preclinical studies. It is widely applied in pharmacological and toxicological research where changes in cholinesterase activity serve as a biomarker. The assay provides a sensitive and specific colorimetric readout, allowing high-throughput analysis in 96-well plate format. Ideal for studies involving drug development, environmental toxin impact, or hepatic disease models in rats.
