Metabolic labeling of proteins in virus-infected HeLa or Vero cells. Cells were either mock infected or infected with KOS1.1 or ΔSma at an MOI of 10. At 5 or 11 hpi, cells were metabolically labeled with [³⁵S]methionine for 1 h. Cell extracts were prepared and analyzed by SDS-polyacrylamide gel electrophoresis and autoradiography. The positions of the molecular mass markers are indicated on the left. (●, cellular protein; ◀, viral protein).
