Fig. 4. MPR300-containing endosomes in control (ct) and µ1A-deficient cells (µ1A–/–). Steady-state labeling for MPR300 is shown in red, and the early endosome antigen 1 EEA1 is shown in green. Quantificaton of the yellow spectra revealed a 2.3 fold more intense staining in µ1A–/– cells compared with ct cells. Labelling of late endosomes with LBPA is shown in red and MPR300 is shown in green. Steady-state labelling for MPR300 (green) and Cy3-labelled transferrin (red) is shown endocytosed over 15 minutes. The distribution of EEA1 (green) and furin (red) is also shown.
