Purexa™ NAEX
Chromatography Membrane
Purexa™ NAEX
for Supercoiled pDNA Capture
A novel weak anion-exchange membrane chromatography product, Purexa™ NAEX has high binding capacity with targeted molecules. For pDNA, Purexa™ NAEX has a high conductivity and impressive recovery during the purification process while successfully removing unwanted impurities.
How Purexa™ NAEX Works
The proprietary structure of tertiary amine ligands on the NAEX membrane binds plasmid DNA at selected buffer conditions and uses high conductivity conditions to release the DNA. Purexa™ NAEX offers consistency across flow rates and multiple cycles while offering:
+ Fast cycle times
+ Easy setup and breakdown
+ High throughput pDNA purification
+ Can be adapted for purifying viral vectors, vaccines, DNA, and proteins
