よくは知らないのですが、crudeですが、下記のboiling methodでプラスミドを抽出したのちエタ沈したものを、DH5aに形質転換できないですかね?
This experiment is called “Boiling method”. In this experiment, STET solution (100 mM sodium chloride, 10 mM Tris-HCl (pH 8.0), 1 mM EDTA, 5% Triton-X or Tween 20) is added to E. coli pellet and suspended well. And then, the sample is heated to 100°C for 1 minute and centrifuged. After centrifugation, plasmid DNA is recovered in the solution, whereas insoluble heat-denatured proteins make debris as pellet fraction. After separating plasmid DNA from debris and precipitating plasmid DNA by adding alcohol, the final plasmid sample is capable for the next experiment. |
