  • Purification of Q Beta replicase
    Patent number: RE35443
    Abstract: A process of producing highly pure, Q Beta replicase having a high level of activity is described. The present process allows isolation of Q Beta replicase from recombinant bacteria containing a clone of a phage DNA encoding the 65,000 weight subunit of Q Beta replicase. The present process provides an efficient method for producing pure Q Beta replicase which can readily be scaled up to commercial production levels.
