Used in immunological research to study the role of CRTAM (Class I MHC-restricted T cell-associated molecule) in T cell activation and immune regulation. This antibody serves as a reference tool for binding assays, flow cytometry, and immunohistochemistry to detect CRTAM expression on activated T cells and NK cells. It supports the development of therapeutic antibodies by providing a benchmark for affinity, specificity, and functional blocking activity. Commonly applied in studies related to autoimmune diseases, antiviral immunity, and cancer immunotherapy to understand cell-to-cell interactions and immune synapse formation.
