Co-localisation of ATP7A and ATP7B with CFDA-Pt. A. Structure of the fluorescent cisplatin analogue (CFDA-Pt) and the platinum-free fluorescein derivative (CFDA-Boc). B. Co-localisation of CFDA-Pt (green) and markers for ATP7A and ATP7B (both red) in A2780 and A2780cis cells. Yellow, the structure is positive for CFDA-Pt and protein markers. Ovals indicate cell periphery. Scale bar, 10 μm.
