Used in bone metabolism studies to measure tartrate-resistant acid phosphatase 5b (TRACP-5b) levels, a biomarker for osteoclast activity. Helps assess bone resorption in research settings, particularly in osteoporosis, Paget’s disease, and other metabolic bone disorders. The ELISA kit enables quantitative detection of TRACP-5b in serum or plasma samples, supporting evaluation of bone turnover and response to anti-resorptive therapies in preclinical and clinical research.
