Bovine pancreatic deoxyribonuclease I produced recombinantly in yeast,
Pichia

pastoris,
to decrease levels of contaminating RNase and eliminate potential pathogens associated with animal based materials.

Bovine pancreas is a rich source of RNase A which is often found in many commercial DNase preparations. Producing DNase I by recombinant means in an organism with much lower levels of endogenous RNase greatly facilitates purification of an enzyme with undetectable levels of RNase. The processes involved in the production and isolation of recombinant DNase I are completely devoid of animal based components which eliminates the possibility of introducing animal derived pathogens into bioprocessing procedures.

Recombinant DNase I is suitable for such applications as:
? Removing genomic DNA from RNA preparations prior to RT-PCR
? Degradation of DNA templates after transcription reactions
? Removing unwanted DNA from samples prior to Northern blotting
? Removing DNA during biopharma and bioprocessing procedures
