(f) Focal accumulation of p62 in the liver of NRBF2 KO mice. Liver frozen sections (15 μm in thickness) were stained with an anti-p62 antibody. Focal accumulation of p62 is observed in the KO mice liver but not in the WT mice liver. Scale bars, 100 μm or 20 μm (amplified regions). This is a representative image from four mice per genotype.
