Molecular Biology Water is prepared by reverse osmosis, passed through fine carbon, deionized through two resin beds, and serially filtered through 0.1 µm positively charged membranes, to yield a product with an endotoxin level of less than 0.03 EU/mL.

  • DNase, RNase and protease tested
  • Endotoxin and mycoplasma tested


Molecular Biology Water is ideal for the preparation of reagents, rinsing glassware and plasticware, and other molecular biology applications where RNase, DNase, and Protease-free water is required.

No toxic agents, including DEPC, are used in the preparation of Molecular Biology Water, eliminating possible interferences with enzymatic reactions. Molecular Biology Water is negative for RNase (sensitivity to femtomoles) and is negative for non-specific Endonuclease, Exonuclease and Protease activity.

Molecular Biology Water is useful in: reconstituting nucleic acids and/or proteins, RNA applications (i.e. Preparation of an RNA probe), DNA applications (i.e. Subcloning in pUC plasmids), and protein applications (i.e. Western Blotting). Molecular Biology Water can also be used as a diluent or solvent for any molecular biology grade biochemical.
