I would suggest including fluorescent beads as internal standard even if the instrument setups are the same for the two types of cells. 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. Clipboard, Search History, and several other advanced features are temporarily unavailable. 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. How are MESF units on the standards determined? These values are only semiquantitative but can be used to standardize experiments between runs or between cytometers. To combat this, geometric mean (gMFI) is often used to account for the log-normal behavior of flow data, however, even gMFI is susceptible to significant shifts. setTimeout(function() {try{el.style.visibility="visible";}catch(err){}}, 2500); MFI is often used without explanation, to abbreviate either arithmetic mean, geometric mean, or median fluorescence intensity. okaBc=6+vH-F+s[jg-;/L.x\Y~*e/W~us>(1qn.Y{@n7 d#}]Kps]D From the panel on the left, select Median or Geometric Mean, and choose the Derived parameter from the panel on the right.
