BD™ CD4 PerCP (100 Tests)
The BD™ CD4 PerCP reagent is designed for in vitro diagnostic use in the identification of cells expressing the CD4 antigen, primarily in flow cytometry applications. This reagent leverages PerCP (Peridinin-Chlorophyll Protein), a fluorescent dye in the BD blue family, to provide high-performance fluorescence for precise cell analysis.
Key Features
- Intended Use:
- For in vitro diagnostics using BD FACS™ flow cytometers equipped with appropriate light scatter and fluorescence detection capabilities.
- Fluorescent Dye (PerCP):
- Excitation Max: 481 nm (excited by blue laser at 488 nm).
- Emission Max: 675 nm (detected using a 695/40 nm bandpass filter).
- Cross-laser excitation can occur with violet lasers (405 nm), resulting in spillover.
- Reagent Details:
- Isotype: Mouse BALB/c IgG1, κ.
- Concentration: 3 μg/mL.
- Volume Per Test: 20 μL.
- Applications:
- Designed for flow cytometry to identify human CD4-positive cells, including T-helper lymphocytes.
- Storage Conditions:
- Stable at 2° to 8°C.
- Do not freeze or expose to direct light.

- Analysis of immune cell populations in human peripheral blood.
- Diagnostic Use:
- For in vitro diagnostic purposes, including monitoring immune system health.
Preparation and Handling
- Store at 2° to 8°C; avoid freezing.
- Protect from direct light to maintain reagent stability.
- Inspect for precipitation or discoloration, which indicates reagent deterioration.
- Ensure the flow cytometer is equipped with the appropriate laser and optical filter configurations for PerCP detection.
Important Notes
- Instrument Compatibility: Ensure the BD FACS™ cytometer is configured to detect the 481 nm excitation and 675 nm emission signals.
- Volume Per Test: Use 20 μL of the reagent for each test.
- Shelf Life: Do not use past the expiration date on the label.
The BD™ CD4 PerCP reagent combines the sensitivity of flow cytometry with the precision of PerCP fluorescence, making it an indispensable tool for immunological studies and diagnostics.
