title: [Inhibition of an immune hemolysis reaction in higher vertebrates by a serum fraction (fraction P) from the pregnant Salamandra salamandra L].
abstract: Serum "fraction P" from Salamandra pregnant female (containing essentially an alpha 2-macroglobulin) possesses non specific cellular immunosuppressive properties [2]. This fraction has been tested in an immune hemolysis reaction: hemolytic Rabbit IgG + guinea-pig complement + Sheep erythrocytes. This fraction, after incubation with guinea-pig complement, inhibits immune lysis.
