- 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)既是一種重要吸附蛋白,介導禽流感病毒吸附和穿入宿主細胞而發(fā)揮致病作用,也是一種良好的保護性抗原,對宿主抵抗禽流感起到了決定性保護作用。
- 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. 研究以干酪乳桿菌作為傳遞抗原活載體表達豬細小病毒主要免疫保護性抗原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. 當sATR溶到細胞外面的液體時(shí)，它們成了有效的誘餌，會(huì )誘拐保護抗原結合過(guò)來(lái)，而不是結合到細胞表面它的真正受體。
