- Study of specific and protective antigens of Taenia solium is the base for diagnosis and immunity of cysticercosis. 猪囊尾蚴特异性和保护性抗原的研究是猪带绦虫病、猪囊尾蚴病免疫和诊断的基础。
- First, protective antigen binds to the surface of a cell, where an enzyme trims off its outermost tip. 首先，保护抗原会结合到细胞表面，然后会有酵素剪掉保护抗原的最外端。
- Aeromonas cytotoxic enterotoxin(act) and outer membrane protein are proved to be the common protective antigens of Aeromonas hydrophila，both are immunogenic. 细胞毒肠毒素（Aeromonas cytotoxic enterotoxin，Act）和外膜蛋白（Outer membrane protein）基因被证明是嗜水气单胞菌的共同保护性抗原，都具有免疫原性。
- Relatively small amounts of selected DNIs neutralized an amount of protective antigen and lethal factor that would otherwise kill a rat in 90 minutes. 只需相当少量选择过的DNI，就可以有效中和掉原本在90分钟内就可以杀死大鼠的保护抗原和致命因子。
- Major protective antigen encoding r egion of E2gene of 2isolate strains o f HCV was amplified by RT-PCR techniq ues and sequenced. 用RT-PCR技术对华东地区2份猪瘟病料的E2基因主要抗原编码区域进行了扩增和序列分析。
- Objective:To find protective antigen(PA) defective mutants of anthrax toxin with the same function as PA but with low immunogenicity,different domains of PA were mutated. 目的:对炭疽毒素保护性抗原(PA)的不同结构域进行了缺失突变,以期找到免疫原性降低而功能变化不大的PA蛋白突变体。

CTA is the toxic subunit, CTB are the nontoxic subunits and the main protective antigen of Cholera. CT是霍乱弧菌主要的致病因子，它是分子量为84KD的肠毒素，由1个A亚单位(Cholera toxin Asubunit，CTA)和5个B亚单位(Cholera toxin B subunit，CTB)形成的五聚体共价连接而成，CTA为毒性亚单位，CTB为无毒的受体结合亚单位，后者是霍乱的主要保护性抗原。

- Lactobacillus casei 393 was selected as oral vaccine carrier for the expression of porcine parvovirus (PPV) major immune protective antigen VP2 protein and immune character was analyzed. 研究以干酪乳杆菌作为传递抗原活载体表达猪细小病毒主要免疫保护性抗原VP2蛋白的免疫特性。
- When sATR molecules are mixed into the medium surrounding cells, they serve as effective decoys, tricking protective antigen into binding to them instead of to its true receptor on cells. 当sATR溶到细胞外面的液体时，它们成了有效的诱饵，会诱拐保护抗原结合过来，而不是结合到细胞表面它的真正受体。
