π-Omega™ Plasmid DNA High-yield Production Platform

PackGene’s proprietary π-Omega™ Plasmid DNA High-yield Platform has increased the plasmid yield by more than 3 times through the plasmid backbone modification. The production scale can reach to 200L, and the single-batch production yield can reach to 100 grams. As a key raw material in AAV production, plasmid DNA cost reduction has greatly reduced AAV production cost, while meeting the growingly plasmids demand in the mRNA therapeutic field.


  • Greatly reduces cost by two-step chromatography
  • High-yield plasmid production through the plasmid backbone modification
  • Strain suitable for mRNA plasmid fermentation (maintaining the stability of polyA)
