Used in biomedical research to quantify osteoprotegerin ligand (OPGL), also known as RANKL, in rat samples. This kit enables researchers to study bone metabolism, osteoclast formation, and related diseases such as osteoporosis, arthritis, and periodontal disease. It is commonly applied in preclinical studies to evaluate the effectiveness of therapeutic agents targeting bone resorption and immune-bone interactions. The assay supports investigation of signaling pathways involving RANK/RANKL/OPG, providing insights into bone remodeling and inflammatory conditions in rat models.
