SAL prevents TPA-induced virus production in B95-8 cells. The permissive EBV-positive marmoset B-cell line B95-8 was treated with SAL 0, 24, 48, and 72 hours after TPA treatment or with TPA, ACY, or DMSO alone. Cells were incubated for a total of 5 days after TPA treatment and assayed for gp350 expression, as described in “Methods.”
