UltraRainbow Calibration Particle Assay

UltraRainbow Calibration Particle Assay (3.8 ± 0.2 µm) is a high-quality standard designed for flow cytometry calibration and performance verification. This kit includes two suspensions: a blank particle suspension (2 × 10⁶ particles/mL, 1 × 3 mL) for background reference, and a fluorescent particle suspension (1 × 10⁷ particles/mL, 1 × 2 mL) for fluorescence detection and instrument alignment. With a uniform particle size of 3.8 µm, these calibration beads ensure accuracy, reproducibility, and consistency in cytometry analysis, supporting applications in cell biology, immunology, and diagnostic research.
