Mouse FZD2, Fc Tag is primarily used in life science research, particularly in studies related to the Wnt signaling pathway. It serves as a critical tool for investigating receptor-ligand interactions, especially in binding assays to identify and characterize Wnt proteins and other potential ligands. Due to the Fc tag, it can be easily detected and purified using anti-Fc antibodies or protein A/G resins, making it highly useful in immunoassays, ELISA, and surface plasmon resonance (SPR) experiments. It is also employed in protein-protein interaction studies and can be used to develop competitive binding assays for screening therapeutic molecules that modulate Wnt pathway activity. Its application extends to structural biology, where it aids in complex formation for crystallography or cryo-EM studies.
