After many times of electrophoresis , the specific protein band of vd - 8 was cutted and the protein was collected as immunogen 在抗原的提取纯化步骤完成之后，要进行单抗的制备步骤。
Applying the x2 test , optimal concentration of the diaphragm antigen was determined , and the optimum dilution of enzyme hrp - spa 1 : 10 本研究确定了抗原的最佳包被浓度为7 . 76ug ml ，酶标spa的最佳稀释倍数为1 ： 10 。
In recent years , the researches indicate that the development of a vaccine based on sperm antigens represent a promising approach for contraception 以精子睾丸抗原为靶抗原的免疫性避孕疫苗因可能适用于两性，一直受到研究者的青睐。
We are now working on the expression and oral vaccination of the hepatitis b virus surface antigen and nucleic antigen by using the expression system in lab 正在利用这一表达体系研究乙肝表面抗原和核心抗原的在乳酸菌中表达及口服免疫。
They can also facilitate the uptake of antigens by apc and this can be explained by the interactions between the surfactant and the cellular membrane 乳剂还能使由apc抗原的摄取更便利，可以通过表面活性剂和细胞膜之间的相互作用对其加以说明。
By pulling receptors away from their surface membrane during signaling , t cells can prevent themselves from being lethally overstimulated by too much antigen 在沟通过程中， t细胞会将受体抽离细胞膜表面，以避免因受到过多抗原的刺激而死于非命。

When injected back into the patients , the antigen - loaded dendritic cells are expected to ramp up patients ' immune response against their own tumors 若把这些载满抗原的树突细胞注射回患者体内，预料这些细胞将可加强患者本身的免疫反应，来对抗自身的肿瘤。
The previous studies have shown that immune response to an antigen will be enhanced greatly when some cytokines are pre - injected or injected together with the antigen 研究表明，若与抗原同时注射或预先注射细胞因子可明显增强机体产生针对该抗原的免疫应答。
The idea of such antigen - stripping goes back to the early 1980s , with the discovery of an enzyme in coffee beans that removes b antigens from red blood cells 早在上世纪80年代期间，科学家就在咖啡豆中发现一种能够脱除红血球b型抗原的酶，并逐步形成抗原脱除的技术思路。
