Abstract:
:The expression of the nuclear SV40-induced T antigen was measured by microfluorimetry on individual, asynchronously growing SV40-transformed cells which had been stained with hamster T-antiserum by the indirect immunofluorescence method. The same individual cells were first measured for T antigen and then for DNA by Feulgen microspectrophotometry. A linear correlation was observed between the two parameters. T antigen expression was also measured in cell populations arrested at different phases of the cell cycle. Results of both types of experiments show that the expression of the gene (s) for T antigen in transformed cells increases during DNA replication and reaches its highest level in G2 nuclei. During mitosis T antigen is found in the cytoplasm.
