UltraPure™ DNase/RNase-Free Distilled Water is designed for use in all molecular biology applications. It is 0.1-μm membrane-filtered and tested for DNase and RNase activity.
Performance and quality testing
No DNase, RNase, or protease activity detected. Our distilled water system is routinely monitored for compliance with current USP monograph test requirements for Water for Injection (WFI).
We do not test for protease activity as part of our QC but there is PMSF (a protease inhibitor) in the storage buffer. Furthermore, in the preparation of DNase I, we use a soybean trypsin inhibitor column to remove proteases.
We perform daily testing of the water according to USP specifications. The USP specification is that conductivity be “not more than 1 micromho/cm”.
