Fluorescence Calibration Calculator

Convert cytometer fluorescence signals to calibrated reference units using your own bead data

Enter Calibration Bead Data

Enter the known reference values (e.g. MESF) and observed MFI for each bead population. The first row is used as background and subtracted from subsequent populations.
