1) Isoelectric points of the guinea pig complement components except Cl and of the C3 inactivator were determined systematically by electrofocusing method. The isoelectric points of the guinea pig complement components were as follow: C4, 5.90; C2, 5.30; C3, 6.25; C5, 5.10; C6, 6.63; C7, 5.78; C8, 6.34; C9, 5.18; and C3 inactivator, 6.45. 2) The distribution curve of each component of the whole guinea pig serum, except Cl, C4 and C2, was a single-peak curve and symmetrical. The discontinuity of these complement components was not observed. 3) The distribution curve of the purified guinea pig complement components, except Cl, and of the C3 inactivator was also of a single-peak curve and symmetrical. 4) It was proved that the electrofocusing meth od was useful for the separation of guinea pig complement components.
