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).
