Negative in breast cancers: EBER1, EBNA1 (Cp/Wp), BHRF1, IR2/BHLF1, LMP1, LMP2A. BC 1=NHS BSP grade II ductal carcinoma; BC 4=mixed pattern carcinoma, ductal elements present; BC 10=high-grade ductal carcinoma; BC 11=ductal carcinoma; BC 12=NHS BSP grade II infiltrating ductal carcinoma; BC 13=NHS BSP grade III invasive ductal carcinoma; 9=cervical lymph node; 14=HD; C15=NPC xenograft (Busson et al, 1988).
