Induction of DNA polymerase activities in the regenerating rat liver

The levels of DNA polymerase α, DNA polymerase δ, and its accessory protein, proliferating cell nuclear antigen (PCNA) were examined in the regenerating rat liver. The levels of DNA polymerase α and δ activities in regenerating liver extracts were determined by the use of the DNA polymerase α specific inhibitor, BuAdATP [2-(p-n-butylanilino)-9-(2-deoxy-β-D-ribofuranosyl)adenine 5'-triphosphate], and monoclonal antibodies
