GMP Plasmid DNA Manufacturing
GMP Plasmid DNA
Driven by a comprehensive quality assurance process, we produce GMP plasmid DNA in segregated ISO-classified manufacturing suites ensuring the highest quality products with each and every order. Combined with dedicated project management and client-specific batch records, we work closely with our clients to provide customized GMP plasmid products.
Our full GMP fermentation capacity ranges from 10 to 1,000 liters. This allows us to offer a complete spectrum of plasmid DNA services, spanning from early research to commercial supply.
