endA+ Strains Plasmid Purification Kits, Biomiga


Biomiga's Plasmid Purification Kit is a  Breakthrough in Plasmid DNA Purification.



  • Superior Purity: This patented Plasmid Purification system uses no chaptropic salts in the buffer, and the resulting purified DNA is free of guanidine salts, cesium chloride, ethidium bromide and ion exchange resin residues, which enable the highest performance of downstream applications including gene therapy and genetic vaccination.
  • Ultra High Yield: When comparing Biomiga' Plasmid Purification System to other purification methods, our methodology produces higher DNA yield while requiring fewer bacterial cultures.
  • Time Saving: Using our unique Megaprep Kit, 10 mg plasmid DNA can be purified from 1,000 mL culture within 1 hour!
  • Environment benefit: The EZgene System is the only method available that does not utilize Guanidine Salt, a hazardous protein denaturant, in the silica based purification system, which will ensure the safety and health of scientists and the environment!


endA+ Strains Plasmid Purification Kits, Biomiga

These plasmid purification kits are especially designed for purifying plasmid DNA from endA+ strains such as HB101, JM101, TG1 or their derived strains.

Unlike other kits in the markets, Biomiga patented plasmid purification kit has no chaotropic salts in the buffer, the purified DNA is guanidine/anion exchange resin residues free which enable the high performance of downstream applications such as transfection, restriction mapping, library screening, sequencing, as well as gene therapy and genetic vaccinations.


The yield of plasmid DNA depends on the origin of the replication and the size of the plasmid. The protocols are optimized for high copy number plasmid purification. For low copy number plasmids, both the culture volume and the buffer volume need to be scaled up 3 to 5 times.
