FIG. 5.
Poliovirus-specific proteins produced by ABCD, ABCd, and abcd viruses in vivo and in vitro. (A) Lysates of infected HeLa cells (MOI = 25 PFU/cell) labeled with [35S]methionine at 4 to 7 h postinfection. (B) In vitro translation products from rabbit reticulocyte lysates programmed with 250 ng of RNA transcripts from ABCD, ABCd, and abcd cDNAs. Noncapsid proteins were identified by their electrophoretic mobilities and band intensities; capsid proteins were identified by their comigration with proteins from purified virions.
