## Abstract We have shown previously that a sequenceβspecific DNAβbinding protein based on the Lac repressor protein can isolate preβpurified DNA efficiently from simple buffer solution but our attempts to purify plasmids directly from crude starting materials were disappointing with impractically
A simple, scalable method for purification of plasmid DNA is described. The method includes modification of the classical alkaline-lysis-based plasmid extraction method by extending the solubilization step from less than 30 min to 24 h. The extraction is followed by the novel use of tangential flow
