Abstract
Fractionation of the poisonous secretion of the toad Bufo marinus paracnemis Lutz, by dialysis and chromatography on QAE-Sephadex, led to the isolation of a fraction which was adsorbed to the ion exchanger. This fraction, when incubated with human serum, yielded an anticomplementary effect that was evaluated by measuring the kinetics of lytic activity on sensitized sheep red cells (classical pathway) and unsensitized rabbit cells (alternative pathway).Entities:
