DNase/RNase Free Distilled water is a high purity water type used for procedures sensitive to the presence of nuclease enzymes. This water undergoes distillation to eliminate contaminants such as DNases, RNases, or other impurities that could otherwise compromise the stability and integrity of molecular biology processes. It is used in a variety of molecular biology applications, including PCR, qPCR, RT-PCR, and other amplification techniques. This product is DEPC (diethyl pyrocarbonate) free.
