Titration of KoRV infection with DERSE cells. DERSE cells were infected with different doses of KoRV (μl of 293T cell supernatant) as in Fig. 1. Fluorescence for GFP-positive cells is shown in a) and SDS-PAGE and western blotting for KoRV Gag and GFP is shown in b. The Gag polyprotein precursor Pr60^gag is indicated, as well as a major proteolytic cleavage product Pr50^gag.
