Other Notes
Small volumes of DNASE2 enzyme vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
Related Product Information for
DNASE2 enzyme
Deoxyribonuclease II is a glycoprotein endonuclease with a dimeric structure. Deoxyribonuclease II from porcine spleen has a molecular weight of 38kD. Optimum pH range is 4.5-5.0 at ionic strength 0.15M. Deoxyribonuclease II (Acid DNase) hydrolyzes deoxyribonucleotide linkages in native and denatured DNA yielding products with 3'-phosphates. It also acts on p-nitrophenylphosphodiesters at pH 5.6-5.9. Bernardi (BBRC, 17, 573, 1971) describes a three stage degradation of native DNA by DNase II.

UniProt Comments for DNASE2
Function: Hydrolyzes DNA under acidic conditions with a preference for double-stranded DNA. Plays a major role in the degradation of nuclear DNA in cellular apoptosis during development. Necessary for proper fetal development and for definitive erythropoiesis in fetal liver, where it degrades nuclear DNA expelled from erythroid precursor cells

By similarity.

Catalytic activity: Endonucleolytic cleavage to nucleoside 3'-phosphates and 3'-phosphooligonucleotide end-products.

Subcellular location: Lysosome.

Miscellaneous: Not required for the generation of the characteristic DNA fragmentation observed in apoptotic cells, but for the degradation of DNA from dying cells.

Sequence similarities: Belongs to the DNase II family.
