The better way
to DNA

PlasmidFactory is the leading contract manufacturer and service provider for plasmid DNA and minicircle DNA.

We understand our clients’ needs – PlasmidFactory is an independent and innovative company that offers a combination of flexibility, reliability, and efficiency.

With research and development competence and expertise in a broad range of scientific fields, meticulous attention to plasmid and minicircle DNA production, a high level of quality awareness, and individual customer support from our dedicated scientists, we understand the needs of our customers and deliver tailored solutions quickly.

This is facilitated by a transparent processing procedure, with our PlasmidFactory specialists available for direct communication at all times.

Driven by our passion for nucleic acids and our scientific curiosity, we are ready to take on extraordinary challenges, combining quality and quantity (High Quality grade pDNA in large scale) and delivering the best possible products for our customers.

PlasmidFactory is not just another plasmid provider.

It is the inventor of a bespoke minicircle technology for AAV and CAR-T cell production, and the only manufacturer that can …

Produce high-purity plasmid and minicircle DNA across a range of quality grades
Generate difficult-to-produce and unstable plasmids and minicircles (e.g. PolyA120, ITRAAV)
Produce up to 10 g of plasmid material per run with low chromosomal DNA impurities
Provide plasmid and minicircle DNA using antibiotic-free fermentation processes
Guarantee a fixed quantity of material, rather than simply selling a production run
Provide AAV 2-Plasmid-System for cotransfection
