KOMBITEST™ CD3 FITC / CD4 PE

The KOMBITEST™ CD3 FITC / CD4 PE reagent is designed for percentage enumeration of mature human helper/inducer T lymphocytes in erythrocyte-lysed whole blood. This test is based on specific binding of monoclonal antibodies to the antigenic determinants expressed on the surface of leukocytes. The monoclonal antibodies are labeled with different fluorochromes which are excited via laser beam from a flow cytometer during analysis. Subsequent emissions of light from fluorochromes of each cell are collected and analyzed by a flow cytometer. The fluorescence intensity differences enable separation of cell subsets based on expression of analyzed antigens.
