title: [Isolation of Ca/Mg-dependent endonuclease of cell nuclei as the basic component in the chromatin nuclease complex of human lymphocytes].
abstract: Highly purified preparations of Ca/Mg-dependent cell nuclear endonuclease have been obtained from human spleen lymphocytes. The purification was 2000-fold, and the enzyme was a polypeptide with a molecular weight of 57-54 kD. The study of its binding with monoclonal antibody enzyme, produced by various hybridoma strains obtained upon the immunization of mice with non-fractionated nuclear extract has shown that Ca/Mg-dependent endonuclease was the best expressed endonuclease of lymphocyte cellular nuclei. Possible production of some other cell nuclear endonucleases during processing of CH/Mg-dependent endonuclease is suggested.
