Bovine Cathepsin L (CTSL) ELISA Kit

The Assay Genie Bovine Cathepsin L (CTSL) ELISA Kit enables quantitative measurement of CTSL across diverse bovine sample matrices using a sensitive immunoassay. Cathepsin L is a lysosomal cysteine protease of the papain family that plays central roles in intracellular protein turnover, MHC class II antigen processing, bone matrix remodeling, and prohormone proteolysis. Dysregulated CTSL activity has been linked to tumor invasion, osteoarthritis progression, lysosomal storage disorders, and viral entry mechanisms in livestock species.

Researchers studying bovine metabolism, reproductive biology, mastitis pathology, and dairy cattle immune function rely on accurate CTSL quantification to characterize protease involvement in disease states. The kit provides 96 assays in a microplate format with all reagents supplied ready-to-use. Sample volume requirements are typically 50 uL per well, and bovine-specific capture and detection antibodies minimize cross-reactivity with homologous cathepsins B, K, and S. Unused components should be refrigerated; reconstituted standards can be stored frozen in single-use aliquots to limit freeze-thaw cycles.
