Deoxyribonuclease I (DNase I) - For RNA work

Grade
Ultra Pure Grade

Description
DNase I is a recombinant form of DNase I which is RNase-free, originally isolated from bovine pancreas, is a recombinant enzyme expressed in Pichia pastoris. It is a DNA-specific endonuclease that hydrolyzes the phosphodiester linkages of double- and single-stranded DNA to a mixture of mono- and oligonucleotides.

DNase I manufactured using state-of-the-art processes yielding animal-free material. The enzyme is highly purified and rigorously tested for contaminating RNase and protease activity of RT-PCR. It is an important tool for all applications requiring DNA-free RNA templates and achieving reliable results with undegraded and stable RNA.
