Used in biomedical research to measure tartrate-resistant acid phosphatase (TRACP) levels in biological samples such as serum, plasma, or cell culture supernatants. This assay is particularly valuable in studies related to bone metabolism, as TRACP is secreted by osteoclasts during bone resorption. The kit enables researchers to assess osteoclast activity in conditions like osteoporosis, Paget’s disease, and bone metastasis. It is also applied in immunological and inflammatory research since TRACP is associated with activated macrophages and dendritic cells. The quantitative detection supports monitoring disease progression and evaluating the effectiveness of therapeutic interventions targeting bone turnover or immune cell activation.
