Lytic expression of vOX2. (A) Flow cytometry analysis of vOX2 surface expression. Unstimulated JSC-1 or TPA-stimulated JSC-1 cells were reacted with an anti-vOX2 antibody, followed by FITC-conjugated anti-mouse immunoglobulin G. As a negative control, unstimulated JSC-1 cells were stained with FITC conjugated anti-mouse immunoglobulin G. Percentages are vOX2-positive cells. (B) vOX2 expression during to KSHV lytic replication. Unstimulated JSC-1, TPA-stimulated JSC-1 cells, or BJAB cell lysates were separated by SDS-PAGE, transferred to nitrocellulose membrane, and reacted with mouse anti-vOX2 antibody, rabbit anti-vIRF antibody, rabbit anti-K8.1 antibody, rabbit anti-MIR1 antibody, and rabbit anti-LANA antibody. As an internal control, donkey antiactin antibody was used.
