来自主题: Biology版 - IC50还是LD50,怎么算?
Btw, I made a mistake, the name should be EC50 (effective concentration).
LD (lethal dose) is usually used in vivo for animal studies.
This is how my lab does EC50: We do 12 point titration either (1/2 or 1/3)
dilution per dilution. For example, for single digit microM compounds, we
do 200 micorM, 100 micorM, 50 microM, for 12 (Log[concentration] will be
your X-axis) points...After that we determine the viability of the cells (Y

来自主题: Biology版 - CRISPR point mutation作出来了
你这样的问题我已经碰到很多人问了。我只能说不容易。我用的donor
不是ssDNA,但怎么克隆一个selection marker进去,又不影响感兴趣基因的splicing,
我还没有想出办法。除非你的突变点靠近后面的UTR,而UTR又比较小,你才有可能加在
你的基因后面。
按我作high-through put的思维,你最好作dilution method,一个well里平均放100个
细胞,然后duplicate每个well, 一个提DNA,PCR,genotyping。再把阳性的well细胞(
duplicate)dilute到single细胞per well,在genotype。这样,你一百个well/PCR能覆
盖10000个单细胞,还没有,就该放弃了。

关于这个standard curve,我想探讨下。
我们老板,要求我们每次qPCR,对每对primer都要用input的dilution做standard
curve。而且要用定量的input做standard curve (10, 1, 0.1, 0.01 ng/ul)然后
sample的定量就用这个standard curve。我觉得更合理的做法是,应该是根据实际IP的
样品量(1/20, 1/200, 1/2000 and 1/2000 of ChIP input)standard curve。这个问
题,跟他争论了好几次,后来就懒得跟他争了。
另外,至于就是是否需要每次都做standard curve?我觉得其实是没有必要的,甚至用
input做standard curve是完全不需要的。standard curve本身的目的就是为了计算
primer的efficiency,以方便定量。其实,模板的量,也会影响primer的efficiency,
primer对input样品的effficiency不一定跟IP样品的一样。而且,qPCR本身是有每次
PCR循环的数据的。根据li... 阅读全帖

来自主题: Biology版 - 请教qPCR cycle 的问题
So how much RNA or cDNA sample do you add to your qPCR? What you do is take
a sample (usually control), do a x2 serial dilution and see if your cycle
is close to a single cycle per dilution and if it is linear. It is call PCR
amplification efficiency. It doesn't have to 100% but I think you should
have >90% and linear.

peptides sure will have different solubility in different solvent. If you

increasing injection volume (10times injection of RPLC) will probably make
those peaks visible.

My personal opinion is
1. Anti-dilution only works for founders who intend to stay and help growth.
if he plans to leave the company permanently, it will be extremely
difficult for him to implement any anti-dilution mechanism at this early
stage of the company. Who is going to invest in the company if there is one
person out there doing nothing but getting 25% of whatever the value the
company creates?

来自主题: Macromolecules版 - SAXS profile calculation
For liquid (polymer in solutions) or crystal sample?
For polymer in solutions, the calculation for concentrated and dilute sample
are different.
Typcially, for concentrated samples, the so-called structure factor will
pollute your scattering profile. (Well, some people may like this
structure factor if they want to study the interactions.)
For dilute sample, things will be much easier. However, you still need
to have an idea of the conformation of your polymer before the calculation.

本来想说这个跟particle的紧密度也有关系,不过感觉象是废话。
pack得太紧,那哪里还有微米尺寸颗粒一说?呵呵。
如果说微米颗粒意味着可以忽略颗粒间的作用的话,感觉颗粒状的情形
应该会有更小的loss。在极端情况下,当颗粒的尺寸小于domain尺寸的
时候,这个就是一个superparamagnets的集合,忽略相互之间的作用,
基本上不会有任何hysteresis的行为(包括magnetization,其名也源于
此),也就不会有由此产生的motion和heat作用。
我觉得比较一下磁性-非磁性合金(显现铁磁性)与相同比例、磁性颗
粒镶嵌在非磁性背景的混合体的差别比较有意思。这几年dilute
magnetic semiconductor就一直有磁性杂质是否uniformly diluted
的争论:有人认为材料中磁性分子很均匀地、分子尺度地分散;而有些
人发现磁性分子形成cluster分布在材料中。我自己做的不是这个方向,
只是组里有人做相关内容,很多具体的东西我不是不太清楚。

日本核事故泄漏的放射物质已到达大温地区! 西门菲沙大学(SFU)研究团队近日在该校位于本那比山以及温哥华市中心校区检测出「辐射雨」,同时在北温码头测得「辐射海藻」,它们含有微量具有放射性的碘-131(iodine-131),相信福岛核事故是唯一来源。 不过研究人员和省府医官皆强调,公众毋须忧虑,目前测得的辐射水平并不足以对人体健康造成危害。
西门菲沙大学在3月19、20及25日的雨水样本检测中,发现碘-131放射活度增加,从原本的每升雨水每秒0贝克(Bq/L)增至10左右。 (西大网站数据)
此外,福岛核电站释放的辐射,亦随风扩散到中国沿岸,广东昨日已测得微量放射性碘-131,香港天文台预测一股气团正由中国东北向南移动,预料在周四上午抵达,不排除会将辐射带到香港。
西大的研究团队称,未来数星期将会继续监测本地的辐射物质。
西大核专家斯塔罗斯塔(Kris Starosta)表示,其研究团队从本月初开始,从西大本那比山上和温哥华市中心两地采集的雨水样本,以及从北温码头附近海域和温哥华岛西岸柏克里湾(Barkley Sound)采集的海藻样本中,监测辐射水平;在本月16日及18日的样本中均未... 阅读全帖

Gary Gereffi and Vivek Wadhwa, is t
