Description
Water, BioScience-Grade, sterile, ready-to-use, nuclease-free, autoclaved, DEPC treated water, Molar mass (M) 18,02 g/mol, Density (D) 1 g/cm³, Boiling point (bp) 100 °C, CAS No. 7732-18-5, EC No. 231-791-2, Empirical formula H2O
Distilled water mixed with DEPC and steam sterilised. By DEPC Histidin residues in proteins are modified to N-carbethoxy histidin, resulting in inhibition of RNases and DNases. DEPC decomposes to CO2 and ethanol during sterilisation. Also available as 50 reaction tubes or as 50 glass ampoules with 1 ml each nuclease free water in a tube rack.To prevent loss of volume in the 1 mltubes (T143.4), we recommend freezing the product at -20°C after receipt.
After autoclaving, each lot is photometrically tested for optimal purity in the wave length range relevant for nucleic acid research.
