Linear fluorescence intensity (relative) = 10 (median log channel)/(channels/decade) Flowjo Analysis of GFP positive cells. An official website of the United States government. National Library of Medicine It must be noted that the values used for fluorescence intensity are not standardized between manufacturers, so this is not a quantitative value in the true sense of the word. All values shown are mean s.e.m. In most cases, the measurement of "relative fluorescence intensity" is adequate, where the fluorescent channel number that best approximates the average fluorescence of one population is compared with the same value from a second population labeled with the same reagent. odata filter multiple ids; why is helianthus paradoxus This means that the distributions, although appearing Gaussian, are actually "log normal" distributions in which the mean fluorescence intensity will be skewed to the right; that is, the mean will overestimate the true average fluorescence intensity.

Histograms A and B show the background expression of CD69 on NK and T cells, respectively, incubated in the absence of the tumor cell lysate. But generally speaking, median is the safest choice and usually most representative of a typical cell. Before The fact is that with potentially millions of data points accrued over the run of a single sample, finding the best way to compare those data can be daunting. and transmitted securely. MFI has many important uses, but can sometimes be as much a distraction from the data as it is a clarification. Do you offer image segmentation or image analysis? Mean and Geometric mean are easiest to understand - here are their formulae (from wikipedia): Mean (aka arithmetic average) is defined as the sum of N things divided by N: If your data is scaled in Log, you might want to use the log-friendly version of Mean, the Geometric Mean.
