Place your calibration standard samples into their own group. View the Project on GitHub broadinstitute/picard. I would suggest including fluorescent beads as internal standard even if the instrument setups are the same for the two types of cells. Ideally, th Multiply the result by the number of antibodies that are used in the flow cytometry assay. As with all indirect measurements, a standard curve must first be created using calibration standards (for example, cytometric bead arrays), to establish the relationship between the fluorescence intensity measurements and the antibody binding to its target molecule.

Median is considered a much more robust statistic in that it is less influenced by skew or outliers. With the standard curve we derive a linear relationship between fluorescence intensity and number of molecules on a given cell. In order to quantify the fluorescence intensity of single cells, we considered a sphere (diameter = 5um) around the tracked location for each cell and at each time point. official website and that any information you provide is encrypted Not sure if you just want to compare the two groups it should work in the way you described it.
