PolyAn’s Spectrum Calibration Beads are designed for calibration of flow cytometers and other fluorescence imaging systems. They are comprised of a set of up to 8 similar size microparticle populations (peaks) with different fluorescence intensities. Each color encoded PMMA bead population (peak) contains a mixture of fluorophores that enable the Spectrum Beads to be excited at any wavelength from 365 nm to 650 nm. PolyAn’s Spectrum Calibration Beads allows the calibration of the FITC, PE, PE-TR, PE-Cy5, and APC channels (or analogue fluorophores) with the same set of particles. The fluorophores are homogeneously encapsulated in the PMMA matrix. A special shell prevents the leaching of fluorophores and thus ensures an optimal shelf-life.

The Spectrum Calibration Beads will be introduced at the AACC / Clinical Lab Expo, August 1st – 3rd, in San Diego, USA. Please visit us at our booth #4601.
