Cytognos Perfect-Count Microspheres™

Visit the website

Perfect-Count Microspheres™ is a microbead-based single-platform system for absolute counts, which can be used in combination with monoclonal antibodies conjugated with different fluorochromes.

Its unique internal quality control contains two bead-types (A and B) that assure the accuracy of absolute counts of cell subpopulations. Type A and B ratio disparity reports possible problems during sample preparation and/or acquisition which might invalidate final results.

Both A and B bead populations are excited by an argon or blue laser (488 nm) but they have different fluorescence intensities that help with their identification in the analysis.
