Abstract

A toxin that causes morphological changes in Chinese hamster ovary cells was isolated from a culture filtrate of Shigella dysenteriae 1. It was partially purified by successive column chromatography on diethylaminoethyl-cellulose, Bio-Gel A-5m, and hydroxylapatite. The toxin was separated from neurotoxin by diethylaminoethyl-cellulose column chromatography and was not lethal for mice.

摘要

从痢疾志贺氏菌1型的培养滤液中分离出一种可引起中国仓鼠卵巢细胞形态变化的毒素。通过在二乙氨基乙基纤维素、生物凝胶A-5m和羟基磷灰石上连续柱层析对其进行部分纯化。该毒素通过二乙氨基乙基纤维素柱层析与神经毒素分离,对小鼠无致死性。
