Abstract
The use of a combination of calibrated microbead populations with one or more calibrated biological cell populations to correct calibration of a flow cytometer for size and fluorescence intensity determinations of biological cell samples. The use of calibrated biological cells permits correction for factors related to the instrument and calibration microbeads so long as the excitation and emission spectra of the calibration microbeads, the calibration cells and the cell samples are all the same, respectively.
