The Measurement of Fluorescence Intensity - Flow Cytometry

WebSince fluorescence intensity often varies several orders of magnitude between cells, the scales are usually the logarithm of fluorescence intensity spanning four decades (a 10,000-fold range). See examples below. In a histogram, the X axis is intensity (of scatter or fluorescence), and the Y axis shows how many cells had each intensity. Thus ... WebFluorescence flow cytometry (FFC) is used to analyse physiological and chemical properties of cells. It can also be used to analyse other biological particles in urinalysis analysers.

WebMFI refers to the Mean, or Median, Fluorescence Intensity. In FCS Express, you may select three statistics to represent MFI for your data. Arithmetic mean, or Average, is the sum of N numbers divided by N. Geometric mean is the Nth root of the product of N numbers. Median, which is the 50th percentile of a population, represents the value at ... Webcells. This is the so-called "secondary control" that marks the level above which fluorescence intensity can be considered specific. Comparing the intensity of cells stained with the secondary antibody alone to the background autofluorescence of unstained cells is often diagnostic of problems with the secondary reagent.

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 to more accurately describe a population of cells in culture.
