| Application【应用】 | Deoxyribonuclease II from porcine spleen has been used in an immunohistological study of the immune system cells in paraffin-embedded tissues. Deoxyribonuclease II from porcine spleen has also been used in a study to investigate its reassociation with the lysosomal membrane. DNase II from Sigma has been used to treat transformed cells during the purification of β-lactamase. It has also been used for the preparation of adenoma tissue in a study that investigated the effect of somatoprim on growth hormone secretion in human adenoma cell cultures (hSA). |
| Biochem/physiol Actions【生化/生理作用】 | The enzyme is a lysosomal acid hydrolase that hydrolyzes DNA to 3′-phosphoryl oligonucleotides in the absence of metal ions, under acidic conditions. It is a non-covalently linked α·β heterodimer of approximately 45,000 Da molecular mass. |
