XMRV seroconversion in RIl-10. (A) Representative antibody responses detected by WB using native XMRV proteins (4 μg/strip) and (B) using mammalian expressed recombinant gp70 (~1.8 μg/strip). Plasma samples from macaque RIl-10 are listed on strips as days post inoculation (PI) with XMRV (0-134). Arrows indicate the first day that detectable reactivity was observed for specific viral proteins. XMRV viral RNA and proviral DNA results [19] are listed above the WB strips. The anti-MuLV pAb (α-F) was used as a positive control. The thin faint band at day 0 in Figure 2B most likely represents non-specific reactivity.
