Used to measure the activity of bovine lipoprotein lipase (LPL) in biological samples such as serum, plasma, or tissue extracts. This assay is commonly applied in metabolic research to study lipid metabolism in cattle, particularly in conditions related to energy balance, such as postpartum negative energy status, ketosis, or fatty liver disease. It helps researchers evaluate how nutritional changes, hormonal signals, or diseases affect LPL function. The kit enables high-throughput analysis in veterinary diagnostics and agricultural research, supporting studies on milk production, feed efficiency, and metabolic health in dairy cows.
