Deoxyribonuclease I (DNase I)

Deoxyribonuclease I (usually called DNase I), originally discovered from bovine pancreas, is a recombinant enzyme expressed in Pichia pastoris. It is a specific endonuclease that acts on single-stranded DNA, double-stranded DNA and chromatin and especially shows a strong preference for double-stranded substrates. It preferentially cleaves DNA at phosphodiester linkages adjacent to a pyrimidine nucleotide, producing tri- and/or tetra-oligonucleotides with 5'-phosphate and 3'-hydroxyl termini. To obtain full enzymatic activity, the pH is approximately 7.5, and micromolar concentrations of Ca²⁺, Mg²⁺, or Mn²⁺ are required. Its molecular mass is around 31-34 KDa depending on the amino acid composition and the extent of glycosylation, both varying in a tissue- and species-specific manner ^[1].

It is important to note that the enzyme needs to function under appropriate conditions, such as:

• 1X DNase I Reaction Buffer
• Incubation at 37 °C

Since the SARS-CoV-2 pandemic, research into the detection and treatment of Coronavirus has never stopped. Alfa Chemistry is committed to providing customers with DNase I used in the nucleic acid detection process to meet their various needs.
