Fig. 2. Localisation of Hrs and EEA1 by confocal immunofluorescence microscopy. A BHK cell stained with anti-Hrs (A) and anti-EEA1 (B) was studied by confocal immunofluorescence microscopy. Yellow colour in the merged image (C) indicates colocalisation. The arrows indicate examples of structures that are strongly positive for EEA1 but negative for Hrs. The arrowheads indicate structures that are positive for Hrs but negative for EEA1. Bar, 5 µm.
