Used in research and diagnostic laboratories to measure the activity of cathepsin enzymes in sheep samples. This ELISA kit enables the quantification of active cathepsins, which are proteolytic enzymes involved in immune response, tissue remodeling, and disease progression. It is particularly useful in veterinary studies, especially in monitoring inflammatory conditions, parasitic infections, and reproductive health in sheep. The assay supports high-throughput analysis and provides a sensitive and specific method for assessing enzyme activity in biological fluids such as serum, plasma, and tissue homogenates. Widely applied in animal health research and biomarker development.
