intensityofeachcell,researcherscandeterminetheROS

levelsintheentirecellpopulation.

OneoftheadvantagesofusingflowcytometryforROS

detectionisitshighthroughputcapability.Thismeans

efficiently,providingstatisticallysignificantresults.

Additionally,flowcytometryallowsforthesimultaneous

analysisofmultipleparameters,suchascellsize,

complexity,andROSlevels,providingacomprehensive
