Can I extract DNA with the SPLIT Kit?

No, the kit is for RNA extraction only. However, since SPLIT is based on acidic phenol-chloroform extraction, DNA and proteins will be located in the lower organic phase. You can attempt to recover and purify DNA from the organic and inter-phases. In order to do so, however, you should omit the use of the Phase-Lock tubes.
