Used in biomedical research to quantify osteoplastin (OPN) levels in biological samples such as serum, plasma, and cell culture supernatants. Widely applied in studies related to bone metabolism, tissue remodeling, and inflammatory diseases. Helps assess osteoblast activity and bone formation processes. Also utilized in cancer research, particularly in understanding tumor progression and metastasis, as OPN is overexpressed in various malignancies. The kit enables high-throughput, accurate measurement with minimal sample volume, making it valuable in clinical research and drug development.
