The CD2 antibody (Clone EP222) is a high-performance rabbit monoclonal antibody developed by GeneBioSolution for immunohistochemistry (IHC) applications on formalin-fixed, paraffin-embedded (FFPE) tissues. CD2 is a transmembrane glycoprotein expressed primarily on the surface of T lymphocytes and natural killer (NK) cells, making it a critical marker in both diagnostic pathology and immunological research. This antibody provides specific and sensitive detection of CD2 antigen, enabling accurate assessment of T-cell lineage, NK-cell activity, and lymphoid architecture. Its optimized formulation ensures crisp membrane staining with low background, delivering reproducible results in both manual and automated IHC platforms. The CD2 EP222 clone is widely used in the evaluation of lymphomas, leukemias, and other hematopoietic malignancies, serving as an essential marker for differentiating T-cell neoplasms from B-cell counterparts. In addition, CD2 expression can be valuable in studying immune regulation, cell adhesion, and receptor-mediated signaling within the tumor microenvironment. GeneBioSolution validates each lot of antibody through strict quality control and tissue panel testing, ensuring high consistency, superior sensitivity, and robust performance across clinical and research settings.
