摘要

A desoxy-ribonuclease substrate is prepared by boiling and homogenizing an aqueous dispersion of high molecular weight desoxy-ribonucleic acid (DNA) and 2-amino-7-dimethylamino-3-methyl diphenazthionium chloride (toluidine blue O) until a clear blue-colored solution is obtained containing a complex compound of the DNA and toluidine blue O. The substrate is used in tests for determination of desoxy-ribonuclease and it's antibodies.
