title: Detection and characterization of DNA-anti-DNA complexes in a patient with systemic lupus erythematosus.
abstract: DNase digestion of SLE serum, with consequent release of bound DNA antibody has been proposed as a method for the direct demonstration of circulating DNA-anti-DNA complexes. In the present studies on the serum of a girl with active SLE nephritis, circulating DNA-anti-DNA complexes were demonstrated at the precise time of relapse of SLE nephritis. Ultracentrifugation showed that these complexes were of low molecular weight.
