Used in immunological research to study the role of butyrophilin subfamily 3 member A3 in human immune regulation. Facilitates investigation of gamma-delta T cell activation pathways due to its involvement in phosphoantigen presentation. Commonly employed in protein-protein interaction assays, binding studies, and structural analysis thanks to the His Tag, which allows for efficient purification and detection. Supports development of therapeutic strategies targeting immune-related diseases and cancers by providing a purified, functional recombinant protein for in vitro and in vivo experiments.
