FIG. 5.
Immunoprecipitation of Erns proteins from SK6 cells infected with different CSFVs. Infected cells were metabolically labeled and the cells lysed with a lysis buffer containing 1% Triton X-100. Proteins were precipitated with an Erns-specific serum and treated with PNGase F, and the deglycosylated precipitates were separated by SDS-PAGE under nonreducing (left) or reducing (right) conditions. The viruses used for infection are indicated above the lanes. The positions of protein size marker bands are given on the left.
