Used for the quantitative determination of HL (hepatic lipase) activity in mouse biological samples such as serum, plasma, or tissue extracts. This ELISA kit enables researchers to measure enzyme activity levels in studies related to lipid metabolism, atherosclerosis, and metabolic disorders in mouse models. It is commonly applied in preclinical research to assess the impact of drugs, genetic modifications, or dietary interventions on hepatic lipase function. The assay provides a sensitive and specific means to monitor changes in HL activity, supporting investigations into cardiovascular disease mechanisms and metabolic syndrome.
