Used in biomedical research to quantitatively measure DKK2 protein levels in biological samples such as serum, plasma, and cell culture supernatants. This ELISA kit is particularly useful in studies related to Wnt signaling pathway regulation, bone metabolism, cancer progression, and developmental biology. It enables researchers to assess DKK2's role in diseases like osteoporosis, multiple myeloma, and certain solid tumors, supporting both basic science and clinical investigation. The assay provides high sensitivity and specificity, making it suitable for detecting low concentrations of DKK2 in small sample volumes.
