WebOne common practice in flow cytometry is the tendency to adjust PMT settings with the specific aim of minimizing percent overlap in the compensation matrix. Remember, the primary goal in setting voltages is to ensure that the resolution between positive and negative is maximized. WebFor this purpose, brightness and spillover remain key issues, as the following example illustrates. Imagine that you want to look at CD62L staining on CD8+ T cells. While CD8 is an abundant protein, and antibodies to it stain cells very brightly, CD62L is relatively “dim” (the protein is not abundant Table 1.
WebCompensation in Flow Cytometry UNIT 1.14 The term “compensation,” as it applies to flow cytometric analysis, refers to the process of correcting for fluorescence spillover, i.e., removing the signal of any given fluorochrome from all detectors except the one devoted … Web1) by double-clicking the compensation badge from the workspace window (any compensated sample has this badge next to the sample in the left hand column down the workspace.) 2) by clicking the “View Matrix…” button in the main …
