title: A new haemolytic assay for the second component of complement (C2) in human serum.
abstract: A new, specific haemolytic assay for C2 is described using EAC43 (Antrypol) cells and serum deficient in C4 and C2 from a patient with hereditary angio-oedema. The method is simple and the results in pathological and normal sera correlate well with those obtained using the EA and C2-deficient serum method.
