EMA Guidelines

EMA Logo

The term “High Quality” is consistent with the meaning embodied in EM(E)A document CHMP/BWP/2458/03 (“Guideline on Development and Manufacturing of Lentiviral Vectors”); EMA document EMA/CAT/80183/2014 (“Guideline on the quality, non-clinical and clinical aspects of gene therapy medicinal products”); and EMA document EMA/246400/2021 (“Questions and answers on the principles of GMP for the manufacturing of starting materials of biological origin used to transfer genetic material for the manufacturing of ATMPs”). PlasmidFactory seeks to ensure maximum safety and the highest quality DNA, although the manufacturing itself is not aligned to GMP standards.

Keeping polyAs intact

PlasmidFactory’s proprietary POLYARESCUE® technology can amplify plasmid DNA containing long polyA stretches. Our Next Generation Sequencing technology complements the optimized fermentation process, allowing sequencing and quantification of polyA sequences while maintaining intact plasmids.

  • Maintenance of long (> 120A) polyA stretches in plasmids
  • DNA template for efficient mRNA production
  • Homogenous product

Scaling up: We offer DNA products of the highest purity in greater quantities than ever.

PlasmidFactory was the first industry to really believe in this (Minicircle) technology. […] They scaled it up and took risks. I think this is what good industry is about, to take risks in a technology you believe in.
