Water

BioScience Grade, nuclease-free, steam sterilised, DEPC treated water
For molecular biology.

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 with 1 ml each nuclease free water in a tube rack.

After autoclaving, each lot is photometrically tested for optimal purity in the wave length range relevant for nucleic acid research.
