QIAGEN Plasmid Plus Kits
The QIAGEN Plasmid Plus Kits enable ultrafast, large-scale purification of up to 10 mg of highly pure plasmid DNA. The use of a vacuum manifold allows purification of up to 24 samples in parallel, reducing hands-on time. Low elution volumes yield highly concentrated plasmid DNA for direct use without ethanol precipitation. The QIAGEN Plasmid Plus Kits also feature a dedicated wash buffer for endotoxin reduction. The plasmid DNA obtained is highly suitable for a multitude of applications, including transfection into sensitive cell lines.
For optimal results it is recommended to use this product together with QIAvac 24 Plus.

QIAGEN Plasmid Kits
QIAGEN Plasmid Kits provide gravity-flow, anion-exchange tips for purification of transfection-grade plasmid DNA. Lysate clearing and isopropanol precipitation are achieved by centrifugation.
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. See more information regarding principle below.
QIAfilter Plasmid Kits
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.

EndoFree Plasmid Kits
EndoFree Plasmid Kits provide anion-exchange-based endotoxin-free plasmid DNA purification. QIAfilter Cartridges enable fast lysate clearing by filtration. The purified DNA exceeds the purity obtained by 2 x CsCl gradient centrifugation and is suitable for advanced transfection-grade applications. The EndoFree Plasmid Buffer Set can be used for preparations of 10 mega or 5 giga transfection-grade plasmid or cosmid DNA preparations.
The Buffer ER in EndoFree Plasmid Kits has been updated to exclude Triton™ X-114, ensuring REACH compliance and even lower endotoxin levels (<0.04 EU/μg) in line with FDA vaccine standards. The improved buffer reduces incubation time from 30 minutes on ice to just 5 minutes at room temperature.*
*Please note: This update includes adjusted Buffer ER volumes and revised incubation times in the protocol.
Plasmid Buffers
Plasmid Buffers are used in plasmid DNA purification procedures. They include Buffer P1 (resuspension buffer), Buffer P2 (lysis buffer), Buffer N3 and Buffer P3 (neutralization buffers), Buffer QC (wash buffer) Buffer QBT (equilibration buffer) and Buffer QF (elution buffer).
