FIG. 7.
Infectivity analysis of MVVE in human PBMCs. (A) PHA-stimulated human PBMCs were inoculated with MVVE (■) or MVVE spiked with AMLV (○) or left uninoculated (▵), and supernatants collected at various times were analyzed by the STF-PERT assay. (B) Linear standard curve of AMV RT standards. The threshold cycle (Ct) for each sample was plotted against the log activity of RT.
