Use of protamine sulphate for elimination of substrate DNA in poliovaccines produced on continuous cell lines.

Abstract:

:Cell substrate DNA was shown to be an abundant contaminant in the clarified preparations of the Sabin type 1, 2 and 3 poliovaccines produced on a continuous cell line (4647). The size of the DNA, as evaluated for the Sabin type 1 poliovaccine, was highly heterogeneous, ranging from 100 to 20,000 base pairs. In view of potential oncogenicity of this DNA a simple and efficient procedure for its elimination is proposed. The method is based on use of protamine sulphate which at the concentration of 2.0 mg ml-1 precipitated cell DNA almost completely without affecting the virus titres.
