Used in research and quality control to measure the activity of Enterokinase (EK) in bovine samples. This ELISA kit enables detection and quantification of active EK, which is essential in biopharmaceutical production where EK is used to cleave fusion proteins. It helps ensure proper enzyme functionality during protein purification processes, especially in recombinant protein expression systems. The assay is valuable for monitoring EK performance in laboratory and industrial settings where precise proteolytic cleavage is required.
