Used in biomedical research to quantify chondroitin sulfate levels in biological samples such as serum, plasma, and tissue homogenates. This kit is particularly valuable in studies related to cartilage metabolism, osteoarthritis, and joint health. It enables researchers to assess changes in chondroitin sulfate concentrations associated with degenerative joint diseases, aging, and therapeutic interventions. The assay supports evaluation of extracellular matrix components in connective tissue research and is applied in preclinical studies of drugs targeting cartilage repair or inflammation. Its high sensitivity and specificity make it suitable for monitoring biomarkers in both experimental models and clinical investigations.
