The CD7-6B7 monoclonal antibody binds to human CD7, a 40-kDa type I transmembrane glycoprotein in the immunoglobulin superfamily. CD7, also known as GP40, is found on T cells, NK cells, thymocytes, and pre-B cells1. CD7 is called T cell leukemia antigen for its expression on acute lymphocytic leukemia and some acute myeloid leukemia2. Studies show that cross-linking of CD7 significantly increases CD7-associated PI3-kinase activity, suggesting the antigen’s functional role in inducing calcium flux in T lymphocytes, and T and NK cell activation3. 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.
