By this procedure, milstein and kohler developed a hybridoma that made a specific antibody . 米尔斯坦和科勒用此方法培养出一个杂种瘤，后来成为一种特效抗体。
The neutralization test is based on the neutralization of virus by specific antibodies found in the serum . 中和试验是基于病毒可被存在于血清中的特异性抗体。
But once the infection is over, antibodies remain in the bloodstream to protect against future attack . 但是一旦感染过后，抗体即留在血液中以防备将来再次的袭击。
The antibody can either neutralize the virus or activate the c system, which lyses virus-infected cells . 抗体或能中和病毒，或能活化补体系统以溶解病毒感染细胞。
A virus can do substantial damage to the body before enough antibodies have been formed to wipe it out . 在尚未形成足够的抗体以消灭病毒之前，这个病毒就能对身体有相当的损害。
Antibodies are produced by the immune system when something foreign, such as viruses or chemicals, invades the body . 抗体是免疫系统在异物（例如病毒或一些化学物质）侵犯机体时所产生的。
If a piece of grafted skin contains an antigen different from the host's, the host will make antibodies against it . 如果一块移植的皮肤含有一种不同于宿主的抗原，宿主将产生抗体来对抗它。
No precipitate is formed if there is an extreme excess of antigen and in some systems, with an extreme excess of antibody . 如果在某些系统中，抗原极度过剩或抗体极度过剩，便不会形成沉淀。
Industry is turning its attention to the possible advantages that monoclonal antibodies may offer for the purification of biological extracts . 工业方面也开始注意到用单克隆抗体纯化生物提取物的优点。
Radioimmunoassy(ria)is one of the most sensitive tehniques presently available for the diagnosis of viral antigens or antibodies . 放射免疫试验（RIA）是目前适合于诊断病毒抗原或病毒抗体的最灵敏技术之一。
