Used for the quantitative measurement of procine CS (chondroitin sulfate) activity in biological samples such as serum, plasma, and tissue homogenates. This ELISA kit enables researchers to assess cartilage metabolism and extracellular matrix changes in studies related to osteoarthritis, joint health, and connective tissue disorders in porcine models. It is commonly applied in veterinary research, pharmaceutical development, and preclinical studies evaluating the efficacy of anti-inflammatory or joint-protective compounds. The assay provides a reliable and sensitive method for monitoring CS levels, supporting biomarker validation and disease progression analysis.
