求审稿机会,为了准备申请绿卡。。Phd期间帮助老板审过七八次。。但
是老板坚持说编辑喜欢让教授审稿或者让以教授的名义让学生审稿,没有跟我推荐任何
的机会。。 发了十几个杂志, 快半年了就只拿到一个审稿机会,剩下的都回复说加了
list就再也没有下文了。。希望大家有
类似方向的推荐一下。。如果需要CV 我可以私下发过去。。大谢!!!
I received my PhD degree in Chemical Engineering at UT-Austin. I have 6
years research
experience in colloids and interface science. Specifically my expertise are
nanoparticle synthesis, colloidal stability, polymer coating/composites,
adsorption, worm-like micelles, emulsions/foams stability, rheology,
Pickering emulsions.
Thanks!... 阅读全帖

we're using Micrel phy chip,
in linux_src/.../drivers/net/phy,
the micrel.c is there, thank God it's the correct chip version for me.
Now i need to make a MAC driver for it.
Where should i get started ? any samples ?
Also why they just put the PHY code there, not the MAC ?
How ppl can use it ?
I hope MAC drivers are just using some generic PHY devices,
then PHY is mapped to Micel in my case.
Any help appreciated.

我没有试过,不知道.你可以自己试一试.
理论上Triton X-100可以把蛋白上associate的SDS洗脱下来形成micelles,然后蛋白可
以得以复性.至于这样对sepharose柱子有什么影响我就不知道了.但是可以试试.

我猜他的意思是有些蛋白提纯的时候会有detergent 带进来,而detergent 本身
因为会形成那种小团状micelle(我为了写那个字都老羞成怒了,不小心就会
被改成michelle),所以个头不小。如果那个蛋白本身也很小的话,用超滤膜就
会出现不能把蛋白和detergent分开的现象。

My guess is as following:
he/she is purifying membrane proteins (or protein complexes). Proper
interaction with detergent is required for its solubility and homogenous
behavior. Otherwise, it is death penalty for crystallization.
If using centricon or amicon, the protein sample will be overly concentrated
at the bottom of the tubes, so will be the detergent. In this case, it
might be over its critical concentration and therefore is likely to form
micelle (I don't have problem with michelle!). At... 阅读全帖

your guess is mostly right.
In my case, because detergent micelle (my detergent has a low CMC) cannot
pass through the concentration membrane and therefore will get concentrated
as well as the protein complex. Subunit interaction will get disrupted and
the protein complex will be broken apart by the high concentration of
detergent.

个人感觉我们对于生物起源的了解实在是太少太少,离我们能够确定的说“生命就是这
样开始的”程度还差的太远太远。作者所说的最多只是一个假说,而作者的很多所谓的
论据都是断章取义,有些故弄玄虚,其实并没有多少说服力:
比如说所谓的“斯皮格曼的怪物”(Spiegelman Monster),没有说清楚实验是在加了
RNA replicase的培养液中;这样经过足够代选择加入的RNA当然最后只剩下和RNA
replicase binding的部分,没什么稀奇;可这和所谓的”原始汤”环境有可比性吗?
氨基酸和其他生命的小分子(核酸、脂类)在地球早期严酷环境中产生(无论在空气、
海洋火山还是火山湖泊中)或者从陨石中带来,这是生命产生的前提,而米勒实验是证
明了这种自然产生的一种可能性。它的意义被作者一句话否定掉了?
又比如说到“黑烟囱”生命起源假说,说到最后是:“只需要用着白给的能量
发明膜就行了。”似乎已经无比简单了。可大哥,你是说要发明含ATPase的lipid膜吗
?大哥,ATpase是个如此复杂的蛋白,怎么说有就有了?而且就算有了,怎么才能遗传
啊? 是得进化出一个RNA 的ATPase吧,... 阅读全帖

“不用Detergent,还是可溶的细菌膜蛋白”?
这会是每个人的都有疑问--为什么没有Detergent就能提纯?还有活性?
(你也没说怎么破碎的 哪里表达的,Assuming是大肠,超声波。)
我估计,可能极少数穿莫蛋白和细胞膜在破碎过程中形成MICELLS,然后过柱子时候被你
拿到了。如果NTA柱子挂了蛋白后变成黄色,或者你的Elute是浅黄色,就很有可能是有
膜成分共同被结合,洗脱了。当然如果及少量,也可能看不到颜色变黄。
不怕麻烦的话,可以挑个简单的实验 加温和的Detergent (OG,DM,等等温和但是CMC
大点儿的),看看结果是不是一样。
Pierce的手册里有很好的关于Detergent的介绍

nod 过滤膜没意义。
其实就先Argue一下好了,根据你说的“这一类蛋白如果提取inverted membrane
vehicle也是有活性的”,再加楼上那个建议
:”
发信人: qianwang (oasis), 信区: Biology
这个蛋白只有两个跨膜区,可能没有detergent对蛋白的活性影响不大。解释一下就可
以了吧“
///另外,如果真要弄清楚,不怕麻烦,还可以吧你的Elute做个冷冻电镜(或者负染?
)看看,如果是
Micelles 会看到一个一个的
小球的。不知道别的手段能不能区分,也许Light Scattering 的机器也能?不过这些
就要工作量了 有时候看值得不值得。

it's not degradation (proteases work less efficiently at ~90C, but will be a
disaster at ~55C at which proteases have reduced activity but protein
substrates begin to open structure and give much higher accessibility), but
precipitation because proteins lose native structure under heating. This is
why SDS or LDS loading bf needs to be added before heating. 1g sds binds to
14g proteins, 10ul sds loading bf is supposed to be enough wrap all proteins

What's your reaction condition? You need to first make the activated NHS
ester PEG Phospholipid (or buy it if you can) in organic solvent. After
that you can do it in PBS buffer etc. If you run the EDC/NHS activation in
water solution, it won't work.

Water, H2O, is a nucleophile. It is competing with your NHS during the
activation. You will get the acid back. EDC activation need to be without
water.

来自主题: Biology版 - 单独表达膜蛋白的跨膜区
第一个建议真的很有用 我一定试试
A和B确实都是一次跨膜蛋白
我也非常怀疑是否是false positive
确实用的NP40 buffer 提全蛋白(7号针头抽吸)
但现在结果是A和B的全长和cleavage都作用
而且cleavage要比全长作用强很多 且cleavage在胞内部分
所以我想这样B cleavage是否就不算膜蛋白 也就不行成micelle
为了避免这种可能 所以做截段看作用位点 这样也能抛开膜蛋白特性
不管如何还是希望尽快确定是false还是true

我觉得大概是这样的
这种两亲高分子与普通的两亲高分子的区别在于
1. 因为它是多肽,所以它可以互相缠绕形成蛋白质样的结构,所以憎水的链节在这里
自组装,起到交联点的作用,而且交联强度的顺序是a-helix> b-strand > random coil
2. 而亲水的链节是带电的,互相排斥,无法靠近
所以一吸一斥,使得高分子链既不能聚集成micell,又不能分散在水里形成溶液,以至
於这种两亲高分子在水中形成独特的hydrogel而不是胶体。
