Absolute counting microspheres are developed for absolute counting of cells or other particles by flow cytometry and cell counters. Absolute counts of cells or other particles are determined by comparing the number of cells (or other particles) to the number of microspheres.

We offer multiple products for cell counting--non-fluorescent series (FC) and fluorescent series (FM). The non-fluorescent microspheres are blank carboxylated polystyrene microspheres applying to single population cells or particles counting. And the fluorescent microspheres are carboxylated polystyrene microspheres with various combinations of internal fluorescent dyes (FITC, PE, APC), suitable for different labeled cell classification and absolute counting.

• Highly homogeneous particle size and fluorescence intensity enhance counting accuracy.

• Single platform testing guarantees counting reliability.

• Easy-to-use and suitable for multiple cell types.
