Abstract
A monoclonal antibody against Streptococcus pneumoniae, designated T4A49, detected a 64,000-molecular-weight protein that was immunologically unrelated to the previously described surface protein PspA. This new protein, designated PspB, was pepsin sensitive and trypsin resistant, as is the R antigen of type 28 group A streptococci.
摘要
一种针对肺炎链球菌的单克隆抗体，命名为T4A49，检测到一种分子量为64,000的蛋白质，该蛋白质在免疫上与先前描述的表面蛋白PspA无关。这种新蛋白质命名为PspB，对胃蛋白酶敏感，对胰蛋白酶有抗性，A组28型链球菌的R抗原也是如此。
