      Description

      BD Tritest™ CD4 fluorescein isothiocyanate (FITC)/CD8 phycoerythrin (PE)/CD3 peridinin chlorophyll protein (PerCP) is a three-color direct immunofluorescence reagent for use with a suitably equipped flow cytometer to identify and determine the absolute counts of mature human T lymphocytes (CD3+), helper/ inducer (CD3+CD4+) T lymphocytes, and suppressor/cytotoxic (CD3+CD8+) T lymphocytes 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.

      Preparation And Storage

      1. Store the reagent at 2–8°C. Do not use after the expiration date shown on the label.

      2. Do not freeze the reagent or expose it to direct light during storage or incubation with cells. Keep the reagent vial dry.

      3. Store TruCOUNT Tubes in their original foil pouch at 2–25°C. To avoid potential condensation, open the pouch only after it has reached room temperature and carefully reseal the pouch immediately after removing a tube. Examine the desiccant each time you open the pouch. If the desiccant has turned from blue to lavender, discard the remaining tubes. Use tubes within 1 hour after removal from the foil pouch and do not use beyond the expiration date indicated on the packaging.
