View our PureLink kits optimized for plasmid research. Note: Gel purification is most efficient with lower % agarose gels, so you will want to stay in the 0.7-0.8% range if possible. For these applications, the contamination from the Qiagen gel extraction kit has never been a problem. You dont want your beautiful cloning result to be ruined by a terrible picture just because you were in a hurry. Can samples lysed in RLT and then stored in the freezer be used on the QIAsymphony?
Products. DNA. The QIAsymphony RNA kit uses RLT plus as lysis buffer. Follow the Agarose Gel Electrophoresis Protocol with the following amendments:. When this happens, DNA remains trapped inside the agarose and cannot be extracted properly. Additionally, our gel extraction results tend to be very poor, even for established methods (such as Qiagen kits) that have worked well in previous labs The DNA that is eluted has good purity and works well for cloning and other molecular biology techniques.
