Superior Transfection Efficiency

HeLa Cells seeded in a 6-well plate were transfected with either 2 or 4 µg of pCI-neo®+GFP plasmid isolated from 100 ml of bacteria culture using the ZymoPURE Midiprep Kit, ZymoPURE Maxiprep Kit, or MN Midiprep Kit. GFP expressin was assessed 48 hours later in cell lysates using western blot and Ponceau S staining. The blot was also probed with an antibody against alpha-Tubulin in order to verify equal loading samples.

Plasmid Purity Redefined

Transfection-grade Plasmid DNA

The EndoZero column eliminates residual endotoxins, yielding plasmid DNA with endotoxin levels below FDA limits for vaccines*. This means plasmid is suitable for sensitive applications like transfection of primary cells, in vivo injections, gene editing and recombinant viral vector production.

* Defined as endotoxins below the FDA limit for vaccines (< 0.04 EU/µg of plasmid DNA)

Colored Buffers Enable Easy, Error-free Preparation

Visualize alkaline lysis and neutralization steps using a patented multi-colored buffer system that enables easy determination of complete cell lysis and neutralization to prevent errors in processing.

Advanced EZ-Flow Spin-Column Technology

Our patented ZymoPURE plasmid purification system features a novel binding chemistry and EZ-Flow Spin-Column design that enables high DNA binding capacity and rapid loading of the lysate and wash buffer via vacuum or centrifuge resulting in the purification of highly concentrated (up to 6 mg/ml) endotoxin-free plasmid DNA directly from a spin-column in only 16 minutes.

Instruction Manual

The ZymoPURE family of plasmid purification kit formats handle different amounts of culture input, ranging from miniprep (≤ 5 ml), midiprep (≤ 50 ml), maxiprep (≤ 150 ml) and gigaprep (≤ 2.5 L).

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 Minipreps, Midipreps and Maxipreps is performed in less than 18 minutes and Gigapreps in 45 minutes. This family of plasmid purification kits feature a patented binding chemistry that enables simple purification of highly concentrated (up to 6 mg/ml) endotoxin-free plasmid DNA using 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 9x using a vacuum manifold or centrifuge. Simply bind, wash, and elute transfection ready, endotoxin-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 endotoxin-free plasmid DNA is ideal for transfection (including sensitive and primary cells), CRISPR-Cas9 and gene editing, lentiviral vectors, adenovirus vectors, AAV vectors, gene therapy, chimeric antigen receptor (CAR) generation, recombinant antibody generation, in vitro transcription, synthetic biology, PCR8, transgenic organism generation and microinjections, molecular cloning, restriction endonuclease digestions, site-directed mutagenesis, plasmid transformation of competent cells, Sanger sequencing, and other sensitive downstream applications.
