title: [Immune complexes DNA-anti-DNA during the course of mixed cryoglobulinemia].
abstract: Plasma and isolated cryoglobulins from ten patients with mixed cryoglobulinemia were studied for the presence of DNA using the diphenylamine reagent test. DNA-like material was detected in all the plasmas tested and it was also present in nine of the isolated cryoglobulins. IgM and IgG components of three cryoglobulins were purified by gel-filtration: anti-DNA activity was detected in IgG fraction (two cases), in IgM and IgG (one case); antigammaglobulin activity was always found in IgM fraction.
