Fig. 2From: Involvement of multiple influx and efflux transporters in the accumulation of cationic fluorescent dyes by Escherichia coliTypical cytograms of the wild-type strain (WT) stained (save for the no-dye control) with diS-C3(5) as described in Methods, along with other knockout strains. Those deleted in atpB or acrA are labelled with the relevant colours. Experiments were performed as described in the Materials and Methods sectionBack to article page
