A simple method was developed for the isolation of primase-free DNA polymerase-alpha from the DNA polymerase-alpha-primase complex of mouse FM3A cells. The polymerase was separated from primase subunits by chromatography on a single-stranded DNA-cellulose column in the presence of 50% etylene glycol. The primase-free DNA polymerase-alpha contained two polypeptides with molecular masses of 180,000 and 68,000. Analysis of the DNA products with poly(dA)-oligo(dT)10 as template-primer revealed that both primase-free DNA polymerase-alpha and the DNA polymerase-alpha-primase complex predominantly synthesized short DNA with less than 30 nucleotides, but that the DNA polymerase-alpha-primase complex also synthesized some longer DNA with more than 300-400 nucleotides.
