Product DetailsRecommended AssayReferencesDescriptionBD Simultest™ CD4/CD8 is a two-color direct immunofluorescence reagent for enumerating percentages of mature human helper/inducer (CD4+) and suppressor/cytotoxic (CD8+) lymphocytes in erythrocyte-lysed whole blood (LWB). The helper/suppressor ratio (CD4+/CD8+) can also be determined.ContentsSpecificityCloneFormatIsotypeEntrez Gene IDCD4SK3 (also known as Leu3a)FITCIgG1, κ920CD8SK1PEIgG1, κ925Resources & ToolsSpectrumViewerDownload MSDSDownload TDSPreparation and Storage• For in vitro diagnostic use.• 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.• The antibody reagent should not be frozen or exposed to direct light during storage or during incubation with cells. Keep the reagent vial dry.• 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.• The antibody reagent contains sodium azide as a preservative; however, care should be taken to avoid microbial contamination, which may cause erroneous results.Clinical Applications of Flow Cytometry: Quality Assurance and Immunophenotyping of Peripheral Blood Lymphocytes; Tentative Guideline.
