Used in biomedical research to quantify osteoprotegerin (OPG) levels in human biological samples such as serum, plasma, or cell culture supernatants. This kit is essential for studying bone metabolism disorders including osteoporosis, rheumatoid arthritis, and bone metastasis. It supports investigation into the RANK/RANKL/OPG signaling pathway, which regulates osteoclast activity and bone resorption. Researchers also use it in clinical studies exploring cardiovascular diseases and diabetes, where OPG levels are often elevated. The assay provides high sensitivity and specificity, enabling accurate measurement of OPG concentrations for diagnostic and therapeutic monitoring purposes.
