Rat Cathepsin S (CTSS) ELISA Kit

This quantitative immunoassay from Assay Genie is purpose-built for measuring Cathepsin S (CTSS) protein in rat-derived samples using a 96-assay plate configuration. Cathepsin S is a lysosomal cysteine cathepsin implicated in antigen processing and presentation through MHC class II pathways, and altered circulating CTSS levels have been reported in rodent models of atherosclerosis, neuroinflammation, and renal injury, making the marker relevant to cardiovascular, neuroscience, and metabolic research programs.

The kit supports quantification across a range of sample matrices relevant to rat studies, including serum-based, plasma-based, tissue homogenate, and cell culture supernatant preparations. Researchers commonly apply this reagent when investigating protease activity in immune cell populations, elastin degradation in vascular studies, or inflammatory cascades in hepatic and pulmonary tissues. Each kit is supplied with pre-coated assay plates, detection antibody, standards, and substrate reagents sufficient for the full 96-assay run. Components should be stored refrigerated between uses to preserve enzymatic conjugate activity, and the reagents are intended for research use only, not for diagnostic or clinical applications.
