Used in research settings to detect and quantify cathepsin L enzyme levels in sheep biological samples such as serum, plasma, tissue homogenates, and cell culture supernatants. This ELISA kit is particularly useful in immunological and veterinary studies focusing on protease activity, tissue remodeling, antigen processing, and inflammatory responses. It enables researchers to investigate the role of cathepsin L in diseases like parasitic infections, arthritis, and certain cancers in sheep models. The assay provides a sensitive and specific method for monitoring changes in cathepsin L expression under experimental conditions, supporting advancements in animal health research and biomarker discovery.
