-
The advantage of this is that now you have four binding sites for antigen instead of just two.
这样的好处是一个抗体上,有四个抗原结合位点而不仅仅是两个
-
So, these are better at binding to antigen because they have more binding sites on them.
连接抗体是对付抗原的有效方法,因为抗体表面将会有更多的抗原结合位点
-
Now, why do you need a cell mediated immune response if you have an antibody response?
为什么你还要有细胞免疫反应呢,你已经有抗体应答了啊
-
There's a lag phase, there's a slow rise to an intermediate level of antibody.
会有迟滞期,在该时期,抗体浓度缓慢到达中间水平
-
I just want to remind you that if you looked at the population of antibodies inside--in your blood, for example, the predominant antibodies would look like this.
我在此提醒下你们,如果你们观察在你们血液中的抗体,主要的一些抗体有以下几种
-
They know that these cells are harboring the virus because those cells have foreign antigens on their MHC1.
它们能知道哪些细胞窝藏病毒,因为这些细胞的MHC1上有外源抗体
-
They also have binding sites for antigen, but they are sort of two IgG type molecules bound together by another peptide chain.
同样IgA抗体表面也有与抗原结合位点,但它们就像两个IgG型分子,通过肽链相互连接
-
They have a region down here called the FC region, and that is responsible for effector functions.
gG抗体有一个区域 被称为FC分区,FC分区负责产生效应
-
So, many--the predominant number of antibodies in your blood look like these IgG molecules.
所以在你的血液中有许多抗体,看上去像IgG分子
-
But not all of them do, there are different kinds of antibody molecules.
但是实际上并不全是IgG分子,这其中包含有很多不同种的抗体分子
-
If you looked later, as the antibody production response matures, some IgG is produced so that in the late period after initial priming you'd have a mixture of IgM and IgG in the blood.
如果你稍后再观察,等到产生抗体的应答趋于成熟后,就会产生一些IgG抗体,在初次免疫的最终阶段,你的血液中有IgM,和IgG两种抗体
