Abstract

After injection of living tetrahymena into the hemocoels of male cockroaches, recovered hemolymph immobilizes washed ciliates. The immobilizing material is sensitive to heat and acid, and can be separated with ammonium sulfate. Hemolymph from immune animals confers protection in another animal into which it is injected. Immobilizing activity of the hemolymph from immune animals is associated with a nonreactive, normal protein component present in hemolymph from nonimmunized insects.

摘要

将活的四膜虫注射到雄性蟑螂的血腔后，回收的血淋巴可使洗涤过的纤毛虫固定。这种固定物质对热和酸敏感，可用硫酸铵分离。来自免疫动物的血淋巴能为注入该血淋巴的另一只动物提供保护。来自免疫动物的血淋巴的固定活性与未免疫昆虫血淋巴中存在的一种无反应性的正常蛋白质成分有关。
