title: [Induction of chemotaxis by soluble immune complexes].
abstract: These complexes, obtained either by adding antigen in excess to immune sera or by redissolving an immune precipitate with antigen, could in the presence of fresh serum stimulate PMN leucocytes to migrate. Complexes with a molecular composition Ab1Ag1 (ot C fixing) showed higher activity than complexes of larger size. The experiments suggest that they activate some sequence of the contact system of coagulation.
