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.
