Table 3.

Comparison of potassium permanganate-pretreatment times in the intensity of FJC and immunofluorescence

Pretreatment time (min) 2 5 7 10
FJC *++++ +++ +++ ++
IF ++++ +++ ++

Note: Intensity of FJC or IF (NeuN): ++++, highest intensity; +++, high intensity; ++, moderate intensity; –; background intensity.

*The intensity of the FJC background was so high that the sample showed a low stain-to-noise ratio.
