Effect of PKH26 staining of U937 cells on adherence to S. Typhimurium. Histograms show the estimated number of bacteria bound per U937 cell. Unlabeled U937 cells (gray); PHK26-labeled U937 cells (black). There was no significant difference (p=0.985) in the number of bacteria bound to unlabeled and labeled U937 cells. Error bars represent standard errors of the mean.
