Flow Cytometry Beads
Flow cytometry beads are specialized microspheres designed for use in flow cytometry to calibrate instruments, standardize assays, and enable quantitative or qualitative analyses. These beads often carry specific fluorescence properties or surface functionalities that mimic biological particles, making them essential for instrument alignment, compensation, and performance validation.
Content on Flow Cytometry Beads
Flow cytometry beads are typically composed of polystyrene or silica microspheres embedded with fluorescent dyes or coated with biomolecules. They are engineered for consistent size, shape, and fluorescence intensity, ensuring reproducibility and reliability in various flow cytometry applications.
Applications of Flow Cytometry Beads
- Instrument Calibration and Alignment:
- Calibration beads with fixed fluorescence intensities ensure proper instrument setup, including voltage, gain, and compensation adjustments.
- Scatter beads mimic cellular populations for accurate forward and side scatter settings.
- Quantitative Analysis:
- Beads with known fluorescence intensity (quantum calibration beads) enable quantification of fluorescence signals in biological samples.
- Compensation Controls:
- Single-color beads are used to correct spectral overlap in multi-color flow cytometry assays.
- Assay Standardization:
- Enable reproducibility in immunophenotyping, cytokine profiling, or other fluorescence-based assays.
- Serve as internal or external controls in experimental workflows.
Flow cytometry beads are indispensable tools for ensuring precision, reproducibility, and accuracy in flow cytometry workflows, supporting both research and clinical applications.
