Used in biomedical research to measure levels of Dickkopf-1 (DKK1) protein in biological samples such as serum, plasma, and cell culture supernatants. DKK1 is involved in regulating the Wnt signaling pathway, which plays a key role in bone metabolism, cancer development, and embryonic development. This ELISA kit helps researchers study diseases like osteoporosis, multiple myeloma, Alzheimer's disease, and various cancers by providing a sensitive and specific method to quantify DKK1 concentrations. It is widely used in clinical research and drug development to assess biomarker expression and monitor therapeutic responses.
