Naturevolume 187pages943944 (1960) | Download Citation



A WATER-SOLUBLE, non-viscous form of deoxyribonucleoprotein has been isolated from purified calf thymus nuclei by a process that minimizes enzyme degradation. Previously the only preparation of deoxyribonucleoprotein generally accepted as undegraded has been the fibrous one, forming gels in water and only slightly soluble, with a molecular weight of 17 million1.
