n. 抗原
[化] 抗原
[医] 抗原
- A protein substance produced in the blood or tissues in response to a specific antigen, such as a bacterium or a toxin. Antibodies destroy or weaken bacteria and neutralize organic poisons, thus forming the basis of immunity.
抗体，免疫体血液或组织针对某种抗原如细菌或毒素而产生的蛋白质物质。抗体消灭细菌或削弱其作用，中和有机毒素，因而形成免疫力 - An antibody produced by or derived from the same species as the antigen with which it reacts.
同种抗体；同族抗体由与抗原相同的种类产生的或衍生的抗体，由它对该抗原作出反应 - Relating to the correspondence between an antigen and the antibody produced in response to it.
同源的与抗原和对其反应产生的抗体同的对应现象有关的
