The RPA-2.10 monoclonal antibody binds to human CD2, a 50-kDa type I transmembrane glycoprotein (1)(2).  CD2, also known as LFA-2, T11, and sheep red blood cell receptor (SRBC-R), is expressed on thymocytes, T lymphocytes, NK cells, and thymic B cell subsets. The major ligand for CD2 is CD58 (also known as LFA-3). CD2 has also been reported to bind CD48, CD59, and CD15. CD2 plays a critical role in alternative T cell activation, T cell signaling, and cell-cell adhesion (3). The antibody was conjugated to a fluorophore and purified by affinity chromatography.

Each lot of this antibody is quality control tested using flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is 5 µL per 1 million cells in a staining volume of 100 µL. If whole blood is analyzed, then use 5 µL per 100 µL. It is recommended that users titrate the antibody to obtain the optimal result for their specific application.
