Used in biomedical research to quantify levels of Human Cartilage Acidic Protein 1 (CRTAC1) in biological samples such as serum, plasma, and tissue homogenates. The kit supports studies related to cartilage metabolism, osteoarthritis progression, and joint health. It is widely applied in clinical research and drug development to evaluate biomarkers associated with degenerative joint diseases. The assay enables high sensitivity and specificity detection, making it suitable for monitoring disease activity and therapeutic response in experimental settings.
