Effect of alkylation on the physical properties of simian virus 40 T-antigen species.

Immunoprecipitates of SV40 large T antigen from SV40-infected or SV40 large-T-antigen-transformed cells contain cyclin A, p33cdk2, and histone Hi kinase activity..

The major core protein (p25) of the human immunodeficiency virus type 1 (HIV-1) was characterized by two-dimensional-gel isoelectric focusing.. The p25 detectable in

It is clear that PAb280 efficiently immunoprecipitated small t but not large T from extracts of wild-type SV40-infected cells even though large T was present in the cell extract in

The association of T antigen with the NPCs is temperature sensi- tive in cells infected with the SV40 tsA58 mutant, with T antigen no longer present in the NPCs at the

Zone velocity sedimentation of [3H]leu- cine- and 32P04-doubly labeled extract from SV40- infected and -transformed

T-antigen (the simian virus 40 A cistron protein) was purified by immunopre- cipitation and electrophoresis on polyacrylamide gels from monkey kidney CV-1 cells infected with

Estimation of T antigen molecular weight from SV40-infected CV1-P cells using random-coil chromatography. The relationships of

A soluble complement-fixing antigen which reacted with hyperimmune monkey sera was present in the fractions prepared from SV40- infected monkey kidney cells, but not in those from
