Abstract
A high-molecular fraction of the O-antigen of Sh. flexneri and Sh. sonnei was isolated from the antigen complex by gel-filtration through Sephadex G-200 and ultracentrifugation. The high-molecular fraction obtained by ultracentrifugation at 105000 g contained no low-molecular components.
摘要
通过Sephadex G - 200凝胶过滤和超速离心从福氏志贺菌和宋内志贺菌的抗原复合物中分离出O抗原的高分子部分。在105000g下超速离心得到的高分子部分不含低分子成分。
