Plasmid DNA was released from Escherichia coli JM109 by lysis (1% SDS, 0.2M NaOH). Then a neutralization solution (3M sodium acetate buffer, pH4.8) was added to precipitate genomic DNA and protein. After the clarification of the lysate, the supernatant was placed in a multicompartment electro...
;CONSTITUTION: A plasmid DNA having super-coil form and suitable for gene recombination use is purified in a short time at a low cost without using harmful reagent by culturing E.coli transformed with a plasmid in a medium at 37°C for 1 night, collecting the microbial cells from the ...

4]breakage of the cell wall followed by either direct transformation of plasmid into E.coli using the crude cell lysate [1]or deproteinization and purification of plasmids by methods employing phenol:chloroform extractions [3,4].In the methods in which DNA is isolated,it is usually of ...
Plasmid copy number plays a significant role in determining the amount of plasmid DNA recovered from the prep. E. coli cultures were transformed with either a low copy or high copy number plasmid and grown for 18 hours in Lysogeny broth then an equal volume of culture was processed, and ...
