Inactivation of Biologically Active ("Endotoxic") Polysaccharides by Fresh Human Serum

Abstract

Insofar as they have been examined, all the endotoxic properties of polysaccharides, irrespective of their source (viz., bacterial, plant or mammalian), were annulled on incubation with fresh human serum but not with heated serum. Moreover, this action of fresh serum was independent of antibody, of complement, and of properdin.
