Used in biomedical research to quantify soluble Receptor Activator of Nuclear Factor Kappa-B Ligand (sRANKL) in biological samples such as serum, plasma, or cell culture supernatants. This ELISA kit helps study bone metabolism by measuring sRANKL levels, which play a key role in osteoclast formation and activity. It is widely applied in osteoporosis, rheumatoid arthritis, and other bone-related disease research. The assay enables researchers to assess the RANKL/OPG pathway activity, monitor disease progression, and evaluate therapeutic responses in preclinical studies. Suitable for mouse models, it supports immunology and bone biology investigations.
