描述
BD Tritest™ CD3 fluorescein isothiocyanate (FITC)/CD4 phycoerythrin (PE)/CD45 peridinin chlorophyll protein (PerCP) is a three-color direct immunofluorescence reagent for use with a suitably equipped flow cytometer to identify and determine the percentages and absolute counts of mature human T lymphocytes (CD3+) and helper/inducer (CD3+CD4+) T-lymphocytes subsets in erythrocyte-lysed whole blood. When used with Trucount™ tubes, absolute counts of these populations can be enumerated from a single tube.
BD Tritest reagent and Trucount tubes can be used with the FACS™ Loader. The reagent can be used with or without an isotype control.
