A MIB-1/CD20-double immunostaining of the paraffin-embedded section (case 8). MIB-1 stains the nuclei, while CD20 stains the cytoplasm and cell membrane. MIB-1/CD20 doubly labelled cells were counted. The mean percentages under three high-power fields was evaluated as the MIB-1 index. Totally, 95.2% of MIB-1 index is found in this slide.
