Flow cytometry spectral overlap

WebApr 5, 2024 · Fluorescence minus one controls (FMOs) are used to account for spectral overlap in multicolor flow cytometry panels. These controls involve staining samples with all but one of the fluorophores in the panel, then measuring the contribution of those fluorophores to the detection channel of interest. FMO controls are crucial for gating ... Web3. Spectral overlap. Selecting fluorochromes with little or no spectral overlap can be conflicting when trying to select the brightest fluorochrome. However, it is worth sacrificing some brightness in one detector to avoid spillover. By ensuring there is minimum overlap, it will decrease the amount of compensation needed. 4. Controls

Webwhen spectral overlap introduces additional noise.1 Compensation, unfortunately, does not remove this noise. The effect of data spread is thus to reduce the resolution sensitivity, and therefore the stain index, for a fluorescence detector that receives spillover from other detector(s). As a result, we can state a second rule of reagent selec- http://web.mit.edu/flowcytometry/www/Becton%20Dickinson%20Multicolor_AppNote.pdf
