p40是曼氏血吸虫虫卵及毛蚴的主要蛋白抗原,分子量为40kDa。迄今,在绝大多数患者和各种品系的小鼠血清中均能测得抗p40抗体,故p40被认为是一个具有广泛T细胞表位的抗原,在此作者采用一系列免疫 p40 is the major protein antigen of Schistosoma mansoni eggs and miracidia, with a molecular weight of 40 kDa. To date, anti-p40 antibodies have been detected in the sera of most patients and of various strains of mice, so p40 is considered as an antigen with a broad range of T-cell epitopes, where the authors used a series of immunizations
