FIG. 9.

Immunohistochemical analysis of ORF S/L in DRG. Sections of formalin-fixed, paraffin-embedded DRG harboring reactivated (A) or latent (B) VZV and a control uninfected fetal DRG (C) were processed as described in the legend to Fig. 8. ORF S/L was detected by immunohistochemistry essentially as described in the legend to Fig. 7 except that levamisole was omitted from the AP detection buffer and nitroblue tetrazolium chloride was the substrate.
