并可以迅速分化为,抗体分泌细胞,记忆细胞在等待第二次信号的到来
-
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, I have a bacteria infection, stimulates my immune system, I start making antibodies that bind to an antigen specific to that bacteria.
所以 如果我被细菌感染了,我的免疫系统被激活,开始制造抗体,这些抗体结合到细菌特异性的抗原上
-
There's a lag period where if I was just looking for antibodies nothing happens for a while.
这中间存在一段迟滞期,如果只过一会就进行观察,抗体的数量不会发生变化
-
Now, we're not thinking about total antibody concentration because you already have a lot of antibodies circulating within your blood and in your fluids.
现在,我们先不考虑抗体总浓度,因为你的体内已存在许多抗体,在血液以及体液中循环
-
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
-
There's - this diagram comes directly from your book, from one of the boxes in the book which describe how you analyze antibody interactions.
这个图表是直接从书上拿来的,来自于书上的一个框图里,这个框图介绍了如何分析抗体的相互作用
-
Well, let me just say for the rest of time where do antibodies come from naturally?
那么 剩下的时间里我们谈谈,抗体是怎样自然产生的
-
It turns out you can use that for lots of things, you can use it to detect the presence of small amounts of chemicals anywhere.
可以将抗体用来做很多事情,可以用来检测,任意地方是否存在某种微量的化学物质
-
Again, these are antibodies that are specific to that antigen or vaccine that we introduced.
我再说一次,这些抗体针对于,我们所接种的抗原或疫苗特异产生
-
We're thinking about the particular antibody that binds to this antigen that you're exposed to.
现在,我们考虑一种特殊的,与你所接触的抗原相结合的抗体
-
It also turns out that they're made stable in these environments like milk and mucus secretions because of this secretory chain which is wrapped around it.
同时,连接抗体还可以,使抗体在像乳汁或是粘液分泌物,这样的体内环境中保持稳定,因为分泌循环系统可以将抗体包裹在内
-
From a technological perspective, antibodies are incredible tools because antibodies are molecules that are specifically designed to bind to a particular antigen or a particular chemical.
从技术角度上来说,抗体是一种令人难以置信的分子,它们被设计来,特异性地结合抗原,或者某种化学物质
-
These are cells that recognize a particular antigen, they're ready to differentiate into antibody.
这些记忆细胞可识别相应的抗原,它们已经准备好分化产生抗体
-
We'll talk about how to use antibodies in that fashion later today in section.
我们将会讨论如何使用抗体,就在今天的分组讨论上
-
We're going to talk more about now how to use antibodies in section today.
我们还要多谈一些,抗体的应用,就在今天的分组讨论上
-
They differentiate, they make many copies of themselves - I'm sorry they proliferate, they make many copies of themselves, and then they differentiate into antibody production machines.
它们开始分化,再制造很多自身的拷贝,对不起应该是先扩增,扩增出很多自身的拷贝,然后分化成为制造抗体的机器
-
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
-
This kind of recognition leads to another effect, what's the effect? Antibody production.
这种识别还产生了另一种作用,什么作用呢 产生抗体的作用
-
The antibodies they make are all specific to the antigen that stimulated them.
它们制造的抗体,对激活它们的抗原来说都是特异性的
-
Basically, injecting it into some test subjects, making sure that they didn't get diseased from it and looking at antibody responses to see if it worked and it did.
他们把疫苗接种到测试对象体内,确定接种者不会感染疾病,同时观察抗体的应答反应,了解疫苗是否有效
-
I realize that this thinking about antigen, antibody combinations and the mathematics of how strongly an antibody binds to a specific antigen, is maybe something that's new to you.
我觉得这些关于 抗原抗体结合,以及,抗体如何强有力地结合抗原的问题,对你们来说很新鲜
-
If this was tetanus, you got this tetanus vaccine when you were young; you get a boost every five or ten years because your antibody levels are starting to fall.
以破伤风为例,小时候,你接种过破伤风的疫苗,每隔五年或十年要再接种一次,这是因为体内的抗体浓度会下降
-
Antibodies are outside of cells circulating in your extracellular fluid.
抗体在细胞外的 细胞外液中循环
-
This is a very potent molecule for binding to antigen.
这个抗体分子就具有强大的抗原结合能力
-
They bind to the antigen that stimulated their production.
它们结合在那些,激活了抗体产生的抗原之上
