BD Sphero™ Rainbow Calibration Particles, 8 Peaks, 3 to 3.4um

• For flow cytometry calibration and alignment
• Have emission spectra compatible with many common fluorophores used for immunofluorescent staining with flow cytometric analysis
• Very small coefficients of variation in both size and fluorescence
• Contain water insoluble fluorescent dyes which are very stable, allowing them to be sterilized by washing with 70% alcohol
• Provided in convenient dropper bottles containing 5mL of particle suspension at a concentration of 10⁷ particles/mL
• Polystyrene
