QIAfilter Plasmid Kits provide anion-exchange-based plasmid purification with bacterial lysate clearing by filtration. Purified DNA is equivalent to that obtained by 2 x CsCl gradient centrifugation and is suitable for transfection-grade applications.
The QIAfilter Plasmid Mega Kit (cat. no. 12281) and the QIAfilter Plasmid Giga Kit (cat. no. 12291) will be discontinued on June 30, 2021. They remain available as long as stocks last.The QIAGEN Plasmid Mega Kit (cat. no. 12181) and the QIAGEN Plasmid Giga Kit (cat. no. 12191) can be used with the QIAfilter Mega-Giga Cartridges (cat. no. 19781) as an optional protocol step for rapid clearing of bacterial lysates by filtration instead of centrifugation.
