Figure 3: Quantification of antibodies co-localized to early endosomes at 6, 24 and 48 hours after antibody addition to the media. Images were taken on fixed cells and number of co-localized antibodies was calculated per cell at a given time point. Events were calculated in 5 cells per time point. Groups were analyzed with one-way ANOVA with Newman-Keuls multiple comparison test. *P<0.05, **P<0.01.
