Plasmid or Cosmid DNA Purification Using HiSpeed Plasmid Midi Kits

This protocol is for preparation of up to 200µg of high- or low-copy plasmid or cosmid DNA using the HiSpeed Plasmid Midi Kit.

A final DNA concentration of up to 0.4µg/µL can be expected, if eluting a high-copy plasmid with 500µL of Buffer TE. eluates from low-copy vectors or dilute samples can be concentrated by spinning in a centrifuge under vacuum, or ethanol precipitation. Low-copy plasmids that have been amplified in the presence of chloramphenicol should be treated as high-copy plamids when choosing the appropriate culture volume.
