Antibodies to homogeneous calf thymus DNA polymerase-beta and calf thymus DNA polymerase-alpha preparations were raised in rabbits. The antiserum against calf thymus DNA polymerase-beta cross-reacts with all vertebrate DNA polymerase-beta preparations tested, but does not cross-react with trypanosome DNA polymerase-beta, DNA polymerase-gamma, terminal transferase, yeast DNA polymerases, and Escherichia coli DNA polymerase I. The antibodies against calf thymus DNA polymerase-alpha cross-react with DNA polymerase-alpha from mouse, human, and chicken, but do not cross-react with DNA polymerase-alpha from sea urchin embryos and Drosophila embryos, DNA polymerase-beta, DNA polymerase-gamma, terminal transferase, yeast DNA polymerases, and E. coli DNA polymerase I.
