Fig. 5From: Visualisation of HER2 homodimers in single cells from HER2 overexpressing primary formalin fixed paraffin embedded tumour tissueHigh magnification STEM images (80,000 x) from neighbouring regions on the same cell differing in their content of HER2 homodimers. a The image shows a total of 4362 detected particles with a density of 823 particles/μm2. b A similar image, recorded only a few microns away from the first image, and with a similar number of labels and label density value (3567 detected particles and 680 particles/μm2). c The g(r) analysis corresponding to A has no peak and thus indicates a lack of HER2 homodimers in this membrane region. d The g(r) for image b reveals a 20-nm peak indicating the presence of HER2 homodimers. Scale bars in a and b: 500 nmBack to article page
