Fig. 2

a Low FOLR1 gene expression in normal tissues (grey) compared to primary ovarian tumours (red) (N numbers indicated in parentheses; The Human Protein Atlas online tool Xenabrowser online tool [35] (Xenabrowser.net). b No membrane or cytoplasmic FRα protein expression on a broad range of normal tissues (N = 142; scale bars = 2.5 mm). Key normal tissue types; fallopian tube (Fa), ovary (Ov), liver (Li), lung (Lu) and kidney (Ki) are highlighted with black boxes and zoomed images shown. c Representative images of ovarian tumour FRα staining (×40 magnification; scale bar = 50 μm).
