Table 1. Experimental design and RNA labeling.

Experiment group	Sample cell line (Cy5)	Control cell line (Cy3)
Stable expression	BJAB-E1	BJAB
Inducible short-term expression	BJAB-tTA-E1 (−Tet)	BJAB-tTA-E1 (+Tet)
Inducible long-term expression	BJAB-tTA-E1 (−Tet)	BJAB-tTA (−Tet)
Tetracycline treatment	BJAB-tTA (−Tet)	BJAB-tTA (+Tet)

RNA prepared from cells expressing EBNA-1 was labeled with Cy-5, while RNA from control cells with Cy-3. Labeled RNA was then co-hybridized on to individual microarray to capture the transcriptional changes induced in EBNA-1 expressing cells.
