The extraction of group A streptococcal antigens by group C phage-associated lysin has been confirmed. In addition to the T antigen the extract contained M-protein, group-specific polysaccharide and mucopeptide antigen which was difficult to remove. This method of extraction of the T antigen was compared with the trypsin method. The latter method was found to be of advantage in giving a pure specific antigen.
已证实用C组噬菌体相关溶素提取A组链球菌抗原。提取物中除T抗原外,还含有M蛋白、群特异性多糖和难以去除的粘肽抗原。将这种提取T抗原的方法与胰蛋白酶法进行了比较。发现后一种方法在获得纯特异性抗原方面具有优势。
