Description

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.

Format

FormatFITC
Excitation SourceBlue 488 nm
Excitation Max494nm
Emission Max520nm

FITC, fluorescein isothiocyanate, is a fluorochrome with a molecular weight of 389 Da. FITC is sensitive to pH changes and photobleaching. Due to nearly identical excitation and emission properties but different spillover characteristics, FITC and Alexa Fluor® 488 cannot be used simultaneously. FITC is relatively dim and should be reserved for highly expressed markers whenever possible.

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.
