Used in bone metabolism research to quantify tartrate-resistant acid phosphatase 5b (TRACP-5b), a biomarker secreted by osteoclasts during bone resorption. The kit enables accurate measurement of TRACP-5b levels in serum or plasma, allowing assessment of osteoclast activity. It is widely applied in studies of osteoporosis, Paget’s disease, and bone metastasis to monitor disease progression and response to therapy. The ELISA format provides high specificity and sensitivity, making it suitable for preclinical and clinical research settings. Also used in pharmaceutical development to evaluate anti-resorptive drug effects on osteoclast function.
