The FITC/PE Compensation Standard is a convenient means of setting two color compensation on a flow cytometer. Each kit contains an Autofluor™ bead, as well as a bead labeled with FITC, a bead labeled with PE, and one labeled with both FITC and PE.

A test requires one drop (50μl) of particle suspension, which is equivalent to ~100,000 particles. Bangs Flow Cytometry Standards are 7-9μm in diameter (unless otherwise noted) to approximate the size of human lymphocytes.
