Peripheral blood lymphocytes were isolated by Ficoll gradient centrifugation (fraction F) ; subsequently the phagocytic and adherent cells were removed and the supernating cell population (fraction FFF) was passaged through IgG anti-IgG columns to obtain a B cell free lymphocyte suspension (fraction FFF-C). Cells from the 3 lymphocyte fractions and from defibrinated whole blood were simultaneously tested for cytotoxic activity against unsensitized IGR 3 target cells (SCMC assay) and IGR 3 cells previously sensitized with a rabbit anti-melanoma IgG (ADCC assay).

Addition of a human serum factor, earlier designated as factor E (6), greatly enhances the efficiency of this lytic system. The component with this activity has been purified to homogeneity (disc and immunoelectrophoresis). In chromatographic fractionations it was inseparable from the fifth complement component, it was inactivated by and reacted with several anti-C5 antisera, and kinetics of inactivation by heat (56°C) and trypsin were the same for factor E and hemolytic C5 activities. It is concluded that factor E is the fifth component of human complement. Guinea pig C5 is not capable of supporting indirect lysis in a comparable manner, for as yet unknown reasons.

In the thymusdependent area PTV caused oedema 12–24 hours after administration.
