The RTS DNase™ kit removes contaminating genomic DNA from RNA preparations while protecting RNA samples from damage during the DNase treatment process. RTS DNase I enzyme is stable at room temperature, eliminating concern about freeze-thaw cycles that may decrease enzymatic activity. The RTS DNase kit also contains a resin that is used to bind and remove the RTS DNase enzyme and divalent cations from the reaction to improve qPCR results. Protection of RNA is ensured, as the kit contains only certified RNase-free reagents and does not require heat, EDTA, or harsh chemicals.
