Used to quantitatively measure Dickkopf-1 (Dkk-1) levels in mouse biological samples such as serum, plasma, or cell culture supernatants. This assay is widely applied in bone metabolism research, particularly in studies related to osteoporosis and arthritis, where Dkk-1 plays a key role in inhibiting Wnt signaling and regulating bone formation. It is also used in cancer research, especially in models involving multiple myeloma and bone metastasis, as elevated Dkk-1 contributes to osteolytic lesions. The kit enables high sensitivity and specificity, supporting reliable detection of Dkk-1 for preclinical evaluation and biomarker discovery in murine models.
