Used to measure lysine (LYS) activity in biological samples from bovine sources, this ELISA kit is widely applied in veterinary research and dairy science. It helps assess protein metabolism and amino acid utilization in cattle, supporting studies on nutrition, feed efficiency, and growth performance. The kit is also used in monitoring metabolic disorders and evaluating the impact of dietary supplements on amino acid profiles. Its high sensitivity allows for precise quantification in serum, plasma, and tissue samples, making it valuable in both research and agricultural applications.
