PMC MFI has many important uses, but can sometimes be as much a distraction from the data as it is a clarification. Importantly, the affect scaling can have on actually visualizing the median value of a population. 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. The bivariate options can be separated into two broad categories; density plots and dot plots. Careers. After reading a lot about it, I decided to include cells with known genome size as a reference. Web(2010). WebIn this article, we describe an alternate strategy that uses the normalized median fluorescence intensity (nMFI), in which the MFI of the stained sample is normalized to the MFI of the negative control, as the reporting term 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.
