Used in immunological research to study the signaling lymphocytic activation molecule family member 7 (SLAMF7), this Fc-tagged protein serves as a critical tool for investigating immune cell interactions, particularly in natural killer (NK) cells and activated B cells. The Fc tag enables easy detection and purification, making it valuable in binding assays, protein-protein interaction studies, and receptor-ligand experiments. It is widely applied in the development and testing of therapeutic antibodies targeting SLAMF7, such as those used in multiple myeloma treatment. Additionally, it supports assay development for drug screening and helps elucidate the role of SLAMF7 in autoimmune diseases and cancer immunotherapy.
