It is a "cute" theory because any single antibody has an idiotype (unique
conformation of amino acid sequences) and could be foreign for the body and
could induce another antibody. This another antibody could do the same and
it goes forever. Based on this theory, all antibodies will eventually be
neutralized by its idiotype antibody.
Jerne (and others) could generate idiotype Ab 1 and Ab 2 to prove his theory
but these idiotype Abs are hardly found naturally, and may not play any

liver. The liver is a big organ in the upper right side of the belly. A

their bodily fluids touch. This can happen in a few ways, like having sex or
sharing needles.
It is estimated that there are more than 300 million carriers of the

sodium Azide at low concentration mainly interferes with the peroxide
reaction (HRP conjugated 2nd antibody). It should be fine to use at a very
low concentration.
After all, it is all up to the antibody. For b-actin, sure freeze and thaw
is fine.
For some delicate antibodies, it will be a big problem.
So for me, unless it is extremely hard to get the antibody, I woudn't reuse

生物版讨论起千青、裙带、争authorship叽里哇啦的上万人看贴,上百人留言讨论。讨
论起真正的生物了,3个人留言,2个外行(不是专家),一个上来什么也不分析就要重
新买抗体。
我也不是专家,专家都在讨论Cui J和内幕,我贡献一下自己的2 cents。
你的staining 肯定有问题。Lyve1只表达在lymphatic endothelium上,不在
macrophage上表达。你如果把图贴出来,可能大家还能帮助你。没有图,我只能猜测有
2个可能:
1)你的F4/80antibody不好。F4/80 antibody有2个clone,一个是CI:A3-1,一个是BM8
。8M8 fix的条件比较tricky,不容易在section 上stain,FACS很好用。如果你用的是
8M8,建议改用CI:A3-1,或者仔细摸一下tissue fixation的时间。Lyve1只有一个
clone (ALY7 ),很亮也很好用。
2)即使你用错了F4/80的antibody,也不应该2个antibody co-localize,LN section

We are talking about science here. Not necessary to comment on others.
LZ did not give much information of his experiment, so what you listed
in below is also pure speculation.
Here I attach a pic what I stained with LYVE-1 in LN,
which is also inflammatory.
The red signal is LYVE-1, blue is B cell region.
Fat should not be problem in isolating LN.
I agree with you that there might be problem of specific staining.
I assume that in the LN of his model, here might be expansion of
both macrophages ... 阅读全帖
