Used for the quantitative determination of Pyruvate Kinase (PK) enzyme activity in sheep biological samples such as blood, serum, or tissue homogenates. This ELISA kit is particularly applied in veterinary research and diagnostics to assess metabolic disorders related to glycolysis, monitor energy metabolism in ruminants, and support studies on diseases like anemia or muscle dysfunction in sheep. It enables high-throughput analysis in laboratories focusing on animal health, nutrition studies, and livestock disease surveillance.
