GeneArt Plasmid DNA Purification Services

Our experienced scientists can prepare research grade plasmid DNA (pDNA) as well as pre-clinical grade plasmid DNA with GeneArt Plasmid Services using proven protocols, quality-controlled systems and reagents.

GeneArt facilities are ISO9001:2018 certified and have demonstrated the ability to consistently provide products and services that meet customer and regulatory requirements. Pre-clinical grade pDNA comes with outstanding quality control and documentation as requested. In addition, cGMP plasmid DNA manufacturing services are available.

Plasmid purification service options

Option 1

Build your own construct with gene synthesis and add plasmid purification.

GeneArt Instant Designer

Also available in the classic geneart portal

Option 2

Re-order or use an archived construct and request purification.

Our highly pure, homogenous plasmid DNA is transfection and/or transformation ready:

  • Extremely low levels of endotoxin: <0.1 EU/µg pDNA in selected scales (generally considered endotoxin-free)
  • Scale production microgram to milligram scale production
  • Production in shaker culture or bioreactor
  • Delivery options: liquid or frozen on dry ice
  • Fill-and-finish service available—get your pDNA in labeled aliquots for immediate use, per your specifications

High performance plasmids are typically high copy number plasmids, production friendly and nontoxic genes that routinely provide greater than 3 mg/L in LB culture.

Table 1. Options of plasmid DNA purification scales with yields. Plasmid purification yields of greater than 1 mg have the option of endotoxin and Bioburden testing.
