FAQ-619
Can the RNase-Free DNase Set be used for DNase digestions of RNA in solution?
Yes. Even though buffer RDD in the RNase-Free DNase Set is optimized for on-column DNase digestion, the buffer is also well-suited for efficient DNase digestion in solution. Please note that the reaction must be cleaned up after the off-column DNase digest to remove the enzyme and buffer RDD, which will interfere with subsequent RT reactions.
A protocol for in-solution DNase digestion using the RNase-Free DNase Set can be found in Appendix C of the RNeasy MinElute Cleanup Handbook. For subsequent RNA Cleanup, use either the RNeasy MinElute Cleanup Kit, or follow the instructions for RNA Cleanup in the RNeasy Mini Handbook.

RNase-Free DNase Set
The QIAGEN RNase-Free DNase Set is guaranteed RNase-free, quality-controlled, and optimized for use with RNeasy procedures and with QIAamp RNA Blood Mini procedures. Generally, DNase digestion is not required for RNA purified with RNeasy Kits since the silica-gel–membrane, spin-column technology efficiently removes the majority of the DNA without DNase treatment. However, more complete DNA removal may be necessary for certain RNA applications that are sensitive to very small amounts of DNA. Buffer RDD, included in the set, is optimized for on-column DNase digestion of 15 minutes at 20–30°C. The buffer is also well-suited for efficient DNase digestion in solution. The RNase-Free DNase Set provides efficient on-column digestion of DNA during RNA purification from cells and tissues using RNeasy Kits and the QIAamp RNA Blood Mini Kit. The DNase is efficiently removed in subsequent wash steps. For DNase treatment when using the RNeasy 96 Kit, please contact QIAGEN Technical Services or your local distributor for a separate, optimized protocol. The QIAGEN RNase-Free DNase Set is delivered as a stable, lyophilized enzyme. The RNase-Free DNase Set provides 1500 Kunitz units.

QIAwave RNA Mini Kit
The QIAwave RNA Mini Kit is an eco-friendlier version of our standard RNeasy Mini Kit. The kit uses up to 60% less plastic and up to 57% less cardboard than our standard kit and offers waste tubes made from 100% post-consumer recycled plastic that you can reuse throughout the procedure. QIAwave buffers also come as concentrates, reducing the amount of plastic by up to 90% per bottle. To save paper, there are no printed protocols in the kit. Instead, you can download the protocols you need from the resources list or by simply scanning the QR code inside the box lid. So, while the kit packaging and components of our QIAwave Kit may look different, it’s as easy to use as the RNeasy Mini Kit, and the chemistry and performance are identical.
Please be aware that you will need sterile glass bottles to store the reconstituted buffers.
In partnership with My Green Lab, we've also assessed the environmental impact of this kit. My Green Lab ACT (accountability, consistency, and transparency) environmental impact factor labels are designed to evaluate and score products on several sustainability criteria. These include:
Manufacturing
Responsible chemical management
Sustainable content within products and packaging materials
Disposal of the packaging at the end of life
Products are scored from 1 to 10 except for energy and water consumption, which are scored as 1 point per kWh or gallon, respectively. A low score means a lower environmental impact (see figures "QIAwave RNA Mini Kit ACT environmental impact factor label US 50/250, EU 50/250 and UK 50/250").
