Purify Plasmid DNA for Every Application
Our Invitrogen plasmid isolation kits offer options to eliminate the challenges raised by multi sample processing. We design our plasmid DNA extraction products to isolate plasmid DNA at the purity and scale you need. Choose from our wide range of high-performing, cost-effective plasmid purification technologies designed to help you overcome common plasmid prep issues, such as low recovery and the presence of impurities.
Robust purification of plasmid DNA, in the amount and purity required for the downstream application of interest, is the key step of protein expression workflow. Learn more about how you can obtain transfection grade plasmid and use them with Gibco ExpiCHO and Expi293 transient mammalian expression systems.
