ZymoPURE Plasmid Purification Kits Product Description

The ZymoPURE plasmid purification kits are the best method for rapid isolation of transfection ready plasmid DNA. Plasmid purification for Mini preps, Midi preps and Maxi preps is performed in less than 20 minutes and Giga preps in 50 minutes. This family of plasmid purification kits feature a patented binding chemistry that enables simple purification of highly-concentrated (up to 3 mg/ml) endotoxin-free plasmid DNA on a spin-column. The streamlined workflow eliminates slow gravity flow anion-exchange columns and isopropanol precipitation steps found in other kits. ZymoPURE plasmid purification kits reduce processing time by up to 7x using a vacuum manifold or centrifugation. Simply bind, wash and elute transfection ready, endo-free plasmid in minutes.

The ZymoPURE plasmid purification kits are optimized to ensure the eluted DNA is free of endotoxins, salt, protein, and RNA, resulting in plasmids that are suitable for use in sensitive applications. ZymoPURE II plasmid purification kits include the EndoZero columns that enable rapid isolation of endotoxin-free plasmid DNA. The resulting endo-free plasmid DNA is ideal for transfection1 (including sensitive and primary cells), CRISPR-Cas9 and gene editing2, lentiviral vectors3, adenovirus vectors3 and AAV vectors3, gene therapy, chimeric antigen receptor (CAR) generation4, recombinant antibody generation5, in vitro transcription6, synthetic biology7, PCR8, transgenic organism generation9 and microinjections10, molecular cloning11, restriction endonuclease digestions, site-directed mutagenesis12, plasmid transformation of competent cells, Sanger sequencing13, and other sensitive downstream applications.

Applications of Use

  1. Transfection experiments (stable transfection and transient transfection) require highly-concentrated plasmid DNA that is free of salt contaminants and endotoxins otherwise transfection efficiency is reduced. An example of ZymoPURE used in transfections:
  2. Koblan, LW, et al., Improving cytidine and adenine base editors by expression optimization and ancestral reconstruction. Nature Biotechnology, 843-846 (2018).

  3. Gene Editing techniques such as CRISPR-Cas9, require the delivery of endotoxin-free, concentrated vectors to ensure high efficiency of plasmid transfection. Examples of ZymoPURE used for gene editing:
  4. Findlay, GM, et al. Accurate classification of BRCA1 variants with saturation genome editing. Nature 562, 217-222 (2018).

  5. Lentivirus, Adenovirus and AAV vector production for use in transduction experiments, require up to four separate plasmids to be transfected into cells. Such a high number of expression plasmids requires purified plasmids that are highly concentrated and endo-free, to ensure high transfection efficiencies.

Whether isolating plasmid from E. coli for a restriction enzyme digest, purifying an entry clone for Gateway cloning, or purifying recombined plasmid from the Gibson cloning reagent mixture, highly pure plasmid DNA is required that is free from contaminants that can inhibit enzymatic reactions.
