ZymoPURE II is plasmid purification reinvented. At the core of our ZymoPURE II technology is a novel binding chemistry and membrane that redefines plasmid purity, reduces processing time by 7 fold, and enables > 1 mg of plasmid to be eluted from a microcentrifuge column.

Anion Exchange vs. ZymoPure II on a time line

Elution means Elution.

Tired of performing tedious alcohol precipitations? With ZymoPURE II, the plasmid DNA is bound onto a spin-column and all of the contaminants are washed away prior to eluting in a microcentrifuge. The resulting eluate is transfection-ready and highly concentrated, so there is no need to remove salts and concentrate the plasmid after elution. Be confident in your elution with ZymoPURE.

Good-bye Gravity Flow.

Say farewell to the drip. Your time is valuable, so why spend it waiting for gravity? With ZymoPURE II, the plasmid DNA is bound onto a spin-column in mere seconds using a vacuum manifold or centrifuge, which completely eliminates the need for slow gravity flow columns.

Highest Customer Satisfaction

Unforgettable Experiences.

scientist with lab coat

"Overall, the kit is really easy to use, quick and the yield was the best I have ever obtained from a midi"

- H.H., MIT

“I love it. Easy to use, good yield. I WILL definitely replace my Q kit with this”

- K.J., Mayo Clinic School of Medicine

“It was very easy to use, taking hours off my prep time. The yield was good, 363 µg & 516 µg from 50 ml cultures, and the quality of DNA was also good. I wish I had more of these kits right now!”

- M.V. University of Pennsylvania

“This kit is exactly what our lab has been looking for”

- H.M., Washington University in St. Louis

“This kit is pretty great, midiprep DNA in about the time it takes to do a miniprep.”

- J.G., Yale University

customer data using

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 NucleoBond® Xtra Midi kit from Macherey-Nagel. GFP expression was assesed 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 of samples.
