Zymo Research - ZymoPURE Plasmid Purification
Simplify the Preparation of Transfection-Grade Plasmid DNA

ZymoPURE Endotoxin-Free Plasmid Purification Kits - Minipreps, Midipreps & Maxipreps

The ZymoPURE plasmid purification kits are the best method for easy and rapid isolation of transfection-grade plasmid DNA in minutes. Plasmid DNA purification using Minipreps, Midipreps and Maxipreps is performed in less than 18 minutes and Gigapreps in 45 minutes. Processing time is reduced by up to 9x using a vacuum manifold or centrifuge. Colored buffers permit error-free visualization and identification of complete bacterial cell lysis and neutralization. 

Eluted DNA is free of endotoxins, salt, protein, and RNA, resulting in plasmids that are suitable for use in sensitive applications, including in vivo injections.

ZymoPURE Plasmid-grade comparison

Transfection efficiency of plasmid prepared using ZymoPURE chemistry compared to two popular endotoxin-free kits from Supplier Q and Supplier MN. HeLa cells seeded in a 96-well plate were transfected with 0.2 µg of pGL3® plasmid isolated from an overnight E. coli culture. Luciferase activity was measured after 48 hours.

Superior Transfection Efficiency

ZymoPure - Superior Transfection Efficiency

Data generated by V.B. at University of Cologne

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.
