DKK1 Recombinant Proteins, Antibodies and Wnt Pathway Research Tools

DKK1 is a secreted antagonist of canonical Wnt signaling and a member of the Dickkopf family, which also includes DKK2, DKK3, and DKK4. These proteins have distinct roles in development, bone homeostasis, and regulation of Wnt signaling. DKK1 interacts with LRP5/6 co-receptors and, in cooperation with Kremen proteins, suppresses β-catenin-dependent Wnt activity. Through this mechanism, DKK1 regulates embryonic development, tissue differentiation, and bone formation. Pathological elevation has been associated with impaired osteoblast activity, plasma-cell disorders, and selected solid tumors, where DKK1 may also influence immune and stromal components of the tumor microenvironment. Other important components of the pathway include Frizzled receptors such as FZD10 and the LRP5/6 co-receptors.

DIMA BIOTECH provides multiple human DKK1 recombinant proteins in Fc- and His-tagged formats for DKK1-LRP5/6-related binding studies, ELISA, SPR/BLI, antibody screening, and affinity characterization. Rabbit monoclonal and reference antibodies validated by ELISA and flow cytometry are available together with biotinylated formats for candidate benchmarking, DKK1 detection, and neutralizing-antibody assay development.
