In order to achieve the rapid high-throughput determination of intracellular lipid content of phaeodacylumtricornutum,the detection conditions were investigated by Nile red fluorescence staining.To establish the optimal dyeing conditions,the 96-well-plates and microplate reader were used to examine the various pretreatment solutions and their usage,the amount of Nile red,the dyeing temperature,time,and the effect of cell concentration on fluorescence intensity.And the relationship between fluorescence inten...
