Abstract Rats were fed a diet containing 2-acetylaminofluorene fot periods of 2–32 weeks, then sacrificed; DNA isolated from their livers was used as template in RNA polymerase… Expand
STUDIES ON THE MECHANISM OF ACTION OF CYCLOPHOSPHAMIDE AND AB-132 WITH THE AID OF RADIOPROTECTIVE AGENTS.
Effects of 5-mercapto-2'-deoxyuridine on the incorporation of nucleosides into RNA and DNA in a primary lymphocyte culture system.
The effects of 5-mercapto-2'-deoxyuridine (MUdr) on DNA synthesis in a primary murine spleen lymphocyte culture system stimulated by phytohemagglutinin (PHA) were studied. Inhibition of thymidine… Expand
QUANTITATIVE TWO-DIMENSIONAL THIN-LAYER CHROMATOGRAPHY OF DEOXYRIBONUCLEIC ACID COMPONENTS.
