Spillover compensation flow cytometry

WebCompensation in flow cytometry is the process of correcting for fluorescence spillover emissions. The detectors, or channels, in the instrument are designed to detect a very … WebThe compensation calculation relies on the fundamental concept that the amount of spillover of a fluorophore (e.g. fluorophore A) into a detector (e.g. fluorophore B) is defined by the ratio of A’s signal in B’s detector to A’s signal in its own detector.
