Representative Immunohistochemistry results of selected OSSN tissues. Panels A-C shows no nuclear staining in the negative controls, Panels D-F show positive cells as dark brown staining of the nucleus with HPV-E6 antibody, as well as positive staining for LMP1 and LANA using EBV-LMP1 hybridoma supernatant and KSHV-LANA specific antibody. Panels G-I shows a higher magnification of 60× compared to panels D-F taken at 40×. Panels J-L are immunohistochemistry results for negative samples showing no detectable staining which would represent positive signals.
