RNase-Free Water is pure, quality-tested water suitable for use in all experiments that require RNase-free water, including PCR, RT-PCR, and real-time PCR, and is included in most QIAGEN PCR and RT-PCR Kits, such as the Taq PCR Master Mix Kit, the HotStarTaq Plus Master Mix Kit, and the HotStar HiFidelity Polymerase Kit. RNase-Free Water is prepared with a proprietary process, which yields RNase-free, deionized water without the use of chemical additives, such as diethylpyrocarbonate (DEPC). RNase-Free Water is provided in RNase-free containers.
