Used in biomedical research to quantify RANKL (Receptor Activator of Nuclear Factor Kappa-B Ligand) levels in biological samples such as serum, plasma, and cell culture supernatants. This kit is essential for studying bone metabolism, osteoporosis, and autoimmune diseases, as RANKL plays a key role in osteoclast formation and bone resorption. It is widely applied in preclinical studies, drug development, and inflammation research to evaluate the effectiveness of therapeutic agents targeting the RANKL/RANK/OPG pathway. The assay enables high sensitivity and specificity, allowing researchers to monitor disease progression and treatment response in experimental models.
