WebFluorescence microscopy imaging speed is fundamentally limited by the measurement signal-to-noise ratio (SNR). To improve image SNR for a given image acquisition rate, … Webcence intensity in the R-PE channel. Consequently, the double-positive and FITC-positive cell populations colocal-ized in the upper right quadrant of the dot plot and the two populations could not be discriminated (Fig. 2A). The aim of multicolor flow cytometry is to properly quantify the fluorescence intensity of each dye with which a
