摘要

A sensitive and versatile assay is described for the nuclear transport of 35S-labeled proteins obtained by the in vitro translation of SP6 plasmid-generated mRNAs. A specific nuclear accumulation of greater than 20-fold is observed for the transformation-related nuclear proteins, p53 and E1b, and the nuclear enzyme, thymidine kinase, whereas transport of the nonnuclear proteins, dihydrofolate reductase and simian virus 40 small t antigen, is negligible within 30 min.
