- 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。
- Its molecular weight is about 84KD. It is composed of one A subunit(CTA) and five same B subunits(CTB). 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。
- Hemaglutinin(HA) is an important absorbent protein and effectiv protective antigen of AIV.It not only mediates AIV to adsorb and penetrate cells,but also makes the host produce immunity against AIV. 血凝素蛋白(HA)既是一种重要吸附蛋白,介导禽流感病毒吸附和穿入宿主细胞而发挥致病作用,也是一种良好的保护性抗原,对宿主抵抗禽流感起到了决定性保护作用。
- 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。
- Bacillus anthracis protective antigen 炭疽保护性抗原
- 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。
