title: Plasmid detection and sizing in single colony lysates.
abstract: A simple and contained procedure for the rapid assay of the presence and size of plasmids similar to Col El is described. Bacteria are picked from an agar plate with a toothpick, lysed with dodecyl sulfate and heat, and placed directly on an agarose gel for electrophoresis.
