Properties of simian virus 40 rescued from cell lines transformed by ultraviolet-irradiated simian virus 40.
Simian virus 40 (SV40) strains have been rescued from various clonal lines of mouse kidney cells that had been transformed by ultraviolet (UV)-irradiated SV40. To learn whether some of the rescued SV40 strains were mutants, monkey kidney (CV-1) cells were infected with the rescued virus strains at 37 C and at 41 C. The SV40 strains studied included strains rescued from transformed cell lines cl...
متن کاملSuperinfection of simian virus 40-transformed permissive cells with simian virus 40.
Evidence that the resistance of simian virus (SV40)-transformed permissive cells to superinfection with SV40 is due to lack of virus uptake is presented. When virus uptake is enhanced, the events of infection proceed as in normal permissive cells, resulting in production of infectious virus.
متن کاملSimian virus 40 T-antigen-related cell surface antigen: serological demonstration on simian virus 40-transformed monolayer cells in situ.
Simian virus 40 (SV40)-transformed monolayer cells were analyzed in situ by indirect immunofluorescence microscopy for the postulated cell surface location of SV40 T-antigen-related molecules. With antisera prepared against purified, sodium dodecyl sulfate-denatured SV40 T-antigen, positive surface staining was obtained when the cells had been treated with formaldehyde before immunofluorescence...
متن کاملInduction of simian virus 40 antigen in BSC1 transformed cells.
Heating to 45 C induced in virus-free clones of simian virus 40 (SV40) transformed BSC(1) cells the synthesis of SV40 viral antigen, as evidenced by immunofluorescence. Up to 3.8% of the cells exhibited viral antigen 72 hr after heating to 45 C for 30 min. Depletion of arginine from the medium of the heated cells enhanced and increased the percentage of cells synthesizing viral antigen to 11%. ...
متن کاملDNA binding properties of a mutant T antigen from the simian virus 40-transformed human cell line simian virus 80.
We investigated whether the T antigen of the simian virus 40-transformed human cell line simian virus 80 ( SV80 ) specifically recognizes DNA sequences of its own template, i.e, the viral sequences integrated in the SV80 cellular genome. In vitro DNA binding experiments clearly indicated that, in contrast to wild-type T antigen, SV80 T antigen does not specifically bind to sites on the integrat...
