PATfix® HPLC pDNA Platform

Rapid at-line analytical chromatography solution for all stages of pDNA processing.

PATfix® pDNA is a high-performance HPLC system, engineered for pDNA isoform and multimer separation using the unique analytical capability of the CIMac® pDNA monolithic column. User guides, validated methods, SOPs and pDNA standards are included. User friendly PATfix® software makes for easy data processing, visualization and sharing.

Item no.:  PAT0029


Continued progress in gene therapy and DNA/RNA-based therapeutics has led to a growing demand for reliable pDNA production processes suitable for clinical applications. Increasing yield and purity in the production of pDNA is a vital step in meeting such demand.

The PATfix® pDNA platform provides valuable analytical insights at all stages of pDNA processing, from upstream production through downstream purification and from process development to production of materials for clinical or commercial applications. At-line analytics support informed, accelerated process development and secure production runs and product quality.
