Molecular Biology Grade (MBG) Water, Ultra Pure 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 is less than 0.03 EU/mL


MBG 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 MBG Water, eliminating possible interferences with enzymatic reactions. MBG Water is negative for RNAse (sensitivity to femtomoles) and is negative for non-specific Endonuclease, Exonuclease and Protease activity.

Molecular Biology Grade 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 Grade Water can also be used as a dilutent or solvent for any molecular biology grade biochemical.
