  3. Single digestion with XbaI and gel run
  4. Gel extraction of the upper band containing [http://partsregistry.org/Part:BBa_K079019 Lac Operator1].
  5. Single digestion with EcoRI and gel run. In this way we open the plasmid in 2 points,loosing the Lac Operator3, remaining the lac Operator1 and 2 into the plasmid.
  6. Gel extraction of the upper band containing [http://partsregistry.org/Part:BBa_K079019 Lac Operator1] e [http://partsregistry.org/Part:BBa_K079018 Lac Operator2].
  7. Further single digestion with PstI and gel run.
  8. Gel extraction of the upper band containing [http://partsregistry.org/Part:BBa_K079018 Lac Operator2]

This protocol was executed for all of the operator library members, [http://partsregistry.org/Part:BBa_K079046 Tet], [http://partsregistry.org/Part:BBa_K079048 Lex] and [http://partsregistry.org/Part:BBa_K079047 Lambda].
