Product DetailsRecommended AssayReferencesDescriptionBD Multitest CD3 fluorescein isothiocyanate (FITC)/CD8 phycoerythrin (PE)/CD45 peridinin chlorophyll protein (PerCP)/CD4 allophycocyanin (APC) is a four-color direct immunofluorescence reagent for identifying and determining the percentages and absolute counts of mature human T lymphocytes (CD3+), suppressor/cytotoxic (CD3+CD8+) T-lymphocyte subsets, and helper/inducer (CD3+CD4+) T-lymphocyte subsets in erythrocyte-lysed whole blood. When used with BD Trucount™ absolute count tubes, these populations can be enumerated from a single tube.ContentsSpecificityCloneFormatIsotypeEntrez Gene IDCD4SK3 (also known as Leu3a)APCIgG1, κ920CD3SK7 (also known as Leu-4)FITCIgG1, κ916CD8SK1PEIgG1, κ925CD452D1PerCPIgG1, κResources & ToolsSpectrumViewerDownload TDSDownload MSDSPreparation and Storage• Store the reagent at 2–8°C. Do not use after the expiration date shown on the label.• Do not freeze the reagent or expose it to direct light during storage or incubation with cells. Keep the reagent vial dry.• Store BD 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.How to Define and Determine Reference Intervals in the Clinical Laboratory; Approved Guideline–Second Edition.
