Flow cytometry is used to obtain quantifiable results in reference to the physical characteristics of single cells. Microspheres are small, non-biological beads that can be used as a (1) standard for flow cytometer instrument calibration, (2) reference for cell or particle size, and/or (3) experimental control for fluorescence emission spillover.

These beads are designed to provide:

  • Consistent instrument performance with minimal data variation for alignment, size calibration, and sorting set-up
  • Convenience to save sample, and set compensation for antibody, reagent, and fluorescent proteins
  • Comparable data between experiments and instruments by setting a standard

Flow cytometry compensation beads

Compensation beads are used as single color controls and can be an alternative for stained single cell controls. Learn about the different beads for multicolor flow cytometry experiments including antibodies, fluorescent proteins, and reagents.

Flow cytometry cell counting beads

Cell counting beads are designed to provide a known quantity of microspheres per known volume. Find beads for cell concentration and absolute counting for mammalian cells, particles, and bacteria.

Flow cytometer calibration and size reference beads

To help ensure collection of reproducible and accurate results, flow cytometer parameters can be set and monitored through the use of standardized beads. Understand the different beads required for flow cytometry sorting parameters, instrument set-up, and daily performance.
