Preparation And Storage

1. For in vitro diagnostic use.

2. When stored at 2° to 8°C, the antibody reagent is stable until the expiration date shown on the label. Do not use after the expiration date.

3. The antibody reagent should not be frozen or exposed to direct light during storage or during incubation with cells. Keep the reagent vial dry.

4. Alteration in the appearance of the reagent, such as precipitation or discoloration, indicates instability or deterioration. In such cases, the reagent should not be used.

5. The antibody reagents contain sodium azide as a preservative; however, care should be taken to avoid microbial contamination, which may cause erroneous results.

Becton Dickinson Immunocytometry Systems (BDIS) CD4 fluorescein isothiocyanate (FITC) reagent is a single-color direct immunofluorescence reagent for enumerating percentages of mature human helper/inducer (CD4+) lymphocytes in erythrocyte-lysed whole blood (LWB) or peripheral blood mononuclear cell (PBMC) suspensions.

FITC
Fluorescein (FITC) is part of the BD blue family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 494-nm and an emission maximum (Em Max) at 518-nm. FITC is designed to be excited by the Blue laser (488-nm) and detected using an optical filter centered near 520 nm (e.g., a 530/30-nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
