Plasmid Midiprep Kits

The kits provide an easy and reliable method to purify plasmid DNA from 50-100 mL bacterial cultures in less than 60 minutes. The DNA is ready for downstream applications such as transfection, RFLP, DNA amplification, and automated sequencing. 

  • Midiprep kit: 100-300 µg of high copy plasmid DNA can be isolated from 50 mL culture.
  • Midiprep-II kit: 200-500 µg of high copy plasmid DNA can be isolated from 100 mL culture.
  • Endofree Midiprep kit:100-300 µg DNA yield. Purified DNA can be used for transfection in endotoxin sensitive cells or microinjection. Endotoxin < 0.1 EU/µg DNA.
  • Endofree Midiprep-II kit: 200-500 µg DNA yield. Purified DNA can be used for transfection in endotoxin sensitive cells or microinjection. Endotoxin < 0.1 EU/µg DNA.
  • ezFilter is used to clear cell lysate instead of centrifugation.

    EasyFilter Plasmid midiprep-II kit (10 Preps)

    EasyPrep™ Plasmid Midiprep-II Kit provides a simple, fast and cost effective method to purify plasmid DNAs from bacterial culture, when amount of the plasmid DNA needed is about 400-500 µg. The kit is especially convenient to use when multiple plasmids need to be purified at the same time, as the use of traditional commercial kits is time-consuming. EasyPrepTM Plasmid Midiprep-II Kit applies DNA-binding-specific matrix, which allows the high efficient binding of DNA, while proteins and other cellular components are easily removed during washing. Plasmid DNAs are easily eluted with Tris buffer or pure water. Plasmid DNAs purified from EasyPrep™ Plasmid Midiprep-II Kit can be used directly for downstream applications such as transfection, restriction mapping, library screening, sequencing, as well as gene therapy and genetic vaccinations.

    EasyPrep™ EndoFree Plasmid Midiprep-II Kit provides a simple, fast and cost effective method to purify plasmid DNAs from bacterial culture, when amount of the plasmid DNA needed is about 500 µg. The kit is especially convenient to use when multiple plasmids need to be purified at the same time, as the use of traditional commercial kits is time-consuming. Key to the kit is our proprietary DNA binding systems that allow the high efficient DNA binding  while proteins and other impurities are removed by wash buffer. Nucleic acids are easily eluted with Elution Buffer. Our proprietary endotoxin removal buffer, Buffer RET, is designed to remove endotoxin by a single washing step without tedious phase partitioning steps. The purified plasmid DNA, with endotoxin level less than 0.1 EU per µg of DNA, is ready for transfection of endotoxin sensitive cell lines and microinjections.
