Used in immunological research to study the regulation of γδ T cell activation, as BTN3A2 modulates immune responses. Employed in protein-protein interaction studies, particularly in checkpoint signaling pathways. Commonly utilized in ELISA, Western blot, and pull-down assays due to the His tag for detection and purification. Supports development of therapeutic antibodies and immune modulators targeting the B7 superfamily. Expressed in recombinant systems for structural and functional analysis in cancer and infectious disease contexts.
