Thermo Fisher, 10977015, UltraPure™ DNase/RNase-Free Distilled Water, 500 mL

UltraPure™ DNase/RNase-Free Distilled Water, 500 mL is used as molecular-biology-grade water for preparing reactions, buffers, dilutions, and other workflows that require low nuclease background. The water is 0.1 µm membrane filtered and tested for DNase and RNase activity. Quality testing also shows no detectable protease activity, helping protect nucleic acids and protein-sensitive reactions from contamination introduced through reagent water. The product is not DEPC treated, which makes it convenient for applications where residual DEPC or its breakdown products are undesirable. The distilled-water system is routinely monitored against current USP monograph test requirements for Water for Injection. This configuration is supplied as one 500 mL bottle, ships at room temperature, and is stored at room temperature. It is suitable for routine PCR, cloning, nucleic acid purification, enzyme reactions, and reagent preparation when a consistent molecular biology water source is required.
