Analysis Note

Protein determined by biuret.

Application

Used for the removal of DNA from protein samples.

Deoxyribonuclease I from bovine pancreas has been used in a study to investigate a two-dimensional zymogram analysis of nucleases in Bacillus subtilis. Deoxyribonuclease I from bovine pancreas has also been used in a study to investigate the effects of minor and major groove-binding drugs and intercalators on the DNA association of minor groove-binding proteins RecA and deoxyribonuclease I.

Preparation Note

Derived from New Zealand-sourced pancreas
