title: [On typing the C3-system: Inhibition of the conversion by EDTA-Na2 (chelaplex III) (author's transl)].
abstract: By addition of EDTA-Na2 (Chelaplex III) to fresh sera the possibility for typing of C3-polymorphism is prolonged. Using a final concentration of 45.6 mmol EDTA-Na2/l the conversion is inhibited, and the C3 determination in serum by means of high voltage electrophoresis succeeds even after storage at room temperature during 6 weeks.
