For example, you can obtain the Median Fluorescence Intensity (MFI) of a population. Ultimately, like any piece of data, MFI should only be applied if you are absolutely certain that it is the best comparison to make, otherwise it is simply clutter on an otherwise clean histogram.

Dear Judith, if you just want to compare the two groups it should work in the way you described it. While the Mean might be most useful when used to describe normal distributions and not bi-modal or multi-modal data, the Median is a non-parametric statistic in that it is a better indicator of the central tendency of your data, regardless of the underlying data distribution. Herein, validation and benchmarks of a FRET-based whole-cell lysate RNase H2 activity assay are presented, including standard conditions and procedures to calculate standardized RNase H2 activity.

Note: In the following example, we assume one bound antibody per molecule, which may not be true depending on antibody class, distance between molecules, and number of targeted epitopes on a given molecule. In contrast, experimentally, the binding of the mAb of interest to the cells of interest is determined by the affinity of the mAb of interest for its specific antigen.
