[Interaction of immunoglobulins with charged biopolymers: significance in the regulation of humoral immunity].


When subjected to ion exchange chromatography on QAE-Sephadex A-50 or gel filtration of Sephadex G-200 under conditions that cause the dissociation of immune complexes at pH 4.05, immunoglobulins both from serum and its immunoglobulin fraction increase their interaction with charged antigens as native DNA and cardiolipin. Ion exchange chromatography also… (More)
