TABLE 2.

EBV genome copy number in different cell lines, quantified by EBNA-1 Q-PCR

Cell line No. of EBV genomes/cell
Determined by Q-PCR From literature (reference)
JY 9 <10a
JC5 5 <10a
X50.7 7 <10a
B95.8 16 Variablea
Raji 31 50 (1)
Namalwa <4 2 (14)

Although numbers were not specifically determined for JY, JC5, and X50.7, most lymphoblastoid cell lines have <10 EBV genome copies/cell (11). B95.8 is a producer cell line with a variable EBV genome copy number.
