Fish Cathepsin L (CTSL) ELISA Kit

This cathepsin L ELISA from Assay Genie delivers quantitative measurement of the lysosomal cysteine protease CTSL in fish-derived samples, with plate-based readout on standard microplate absorbance instrumentation. The binding protocol is calibrated exclusively for fish species reactivity and supports research into protein turnover, innate immunity, and stress physiology in aquatic vertebrates. The kit accommodates multiple fish-derived input matrices including tissue homogenates, cell lysates, and cell culture supernatants, enabling aquaculture health monitoring, toxicology screening, and immunological characterization of teleost models where cathepsin L activity serves as a biomarker for inflammatory status and lysosomal disruption. Each kit supplies reagents sufficient for 96 determinations, and the components are configured for fish-specific use in laboratory ELISA workflows, supporting quantitative protein measurement across experimental fish cohorts. The assay is intended for research use only and supports studies of inflammatory cascades, lysosomal function, and welfare biomarkers in farmed or wild fish populations.
