Aurum Plasmid Mini Purification Module
Isolate plasmid DNA from transformed bacteria. Students inoculate minipreps with transformed bacterial colonies from their agar plates. They then isolate plasmid DNA using a three step alkaline lysis procedure followed by mini column chromatography. Purification can be carried out in microcentrifuges or using the Aurum vacuum manifold.
Once plasmid DNA is eluted, students verify insertion of the PCR product into the plasmid vector using restriction enzyme digestion analysis and agarose gel electrophoresis. Bgl II restriction enzyme, specific for screening the pJET1.2 plasmid, is supplied in the Ligation and Transformation module. Students can also determine plasmid DNA concentration using spectrophotometry or fluorometry in an optional step.
