Specific antigen of tumor cell transformed by DNA extracted from SV-40 virus.
In the immunofluorescent study it has been revealed that rabbit sera immunized with transformed cells induced by SV-40 DNA, produce circulating antibody capable of re:lcting with intranuclear antigens synthesized by SV-40 complyte virus transforming process, In addition, the result confirmed that SV-40 DNA replicates DNA-containing viruses in the host cell and that also the genome coding for th...
متن کاملHuman Thymidine Kinase
Cytosolic thymidine kinase (EC 2.7.1.21) has been purified 5200-fold to apparent homogeneity from normal human placenta. The purification includes sequential affinity chromatography on blue-Sepharose and a thymidine column. The molecular weight of the enzyme determined by gel filtration and sucrose density ultracentrifugation is 92,000. The subunit molecular weight is 44,000, suggesting that t...
متن کاملElectron microscopic studies of replicating SV 40 DNA.
Electron microscopic observation of replicating SV 40 DNA has revealed the existence of two types of RF, e form and (1 form. The frequency of RF at 54 hours after infection was 8.9% for the e form and 4.3% for the (1 form. Morphological evidence exhibits that in (1 form RF the tails are, predominantly, shorter than the viral genome and double length SV-40 genomes are also capable of replication...
متن کامل22 SV 40 and Polyomavirus DNA Rep 1 icat ion
The papovavirus family comprises two virus subgroups: the polyomaviruses and the papillomaviruses. The polyomavirus subgroup consists of a dozen members and includes simian virus 40 (SV40), the murine polyomavirus (PyV), and two human isolates, JCV and BKV (for review, see Tooze 1980). The polyomaviruses display strict species specificity for their replication, but otherwise share a common arch...
