The measurement of relative fluorescence intensity in this case is quite adequate for the required purpose, but to compare experiments run on different days or between collaborating centers, it is valuable to have some form of semiquantitative measurement. Blindly using MFI as a quantification of expression: While FACS is more than sensitive enough to provide estimates of ligand abundance, such calculations require normalization and calibration using a standard curve. Statistics aside, gating each population and presenting percentages will yield data that is both more easily interpretable as well as more statistically significant.

WebThe fluorescence intensity of IBA-1 was significantly stronger in the CLP mice, while anti-Gr-1 treatment certainly reversed this change (Fig. A relative fluorescence intensity may be calculated by expressing the increased CD69 expression as a percentage of the level of expression on the T cells as follows: Plainly, the NK cells have shown considerably greater activation in response to the tumor cell lysate than the T cells and the relative fluorescence intensities of the two populations can be compared with each other or with their nonstim-ulated state. Data in a,b are mean +/ s.d. identify an inducible morphotype that facilitates organ entry by the pathogenic fungus Cryptococcus neoformans. Fluorescence for hTERT-Alexa 647 is quantitatively expressed here as the ratio of median fluorescence intensity in CD34 + progenitor cells compared with that in the reference population of lymphocytes in the CD45 + population from the same sample. 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. Copy the statistic to the desired group or gates. Change the plot to a histogram with the primary channel on the X-axis. Human embryonic stem cells (hESCs) are a promising cell source for tissue engineering and regenerative medicine, but before they can be used in therapies, we must be able to accurately identify the state and progeny of hESCs.
