Mouse DKK3, His Tag is primarily used in life science research, particularly in studies related to Wnt signaling pathways. It serves as a valuable tool for investigating cell differentiation, embryonic development, and tissue homeostasis. Due to its role as an antagonist of the Wnt pathway, it is employed in assays examining cancer progression, bone formation, and stem cell regulation. The His tag facilitates easy detection and purification, making it suitable for use in protein-protein interaction studies, ELISA, and immunoprecipitation experiments. It is also used in generating antibodies or as a control in expression analysis.
