比如这道:
Carter leases a building from U Co., and management of Carter decides to
cancel the lease. Which section of the professional standards addresses the
issue of valuing the liability for the termination costs related to
canceling the lease?
我有becker光盘上的library可以查看,就这道题来说我用了关键词"cancel lease,
liability,cost"都查不到正确答案:420 10 30 7-8。
这道题应该怎么输入关键词才好查出答案来呢?谢谢!

来自主题: Biology版 - Re: what is phage display library?
If you clone a 30 bp DNA into the 5' of the filamentus phage
gene III or VIII, it will express a 10 Aa peptide on the surface
of the phage partical. So if you have a libray of random sequence
30bp DNA, you're able to get a libray of phage with each of
them express a different random 10 Aa peptide on the surface.
That is a 10Aa phage display library.
If you have a ligand and you're able to immoblize it on the coloumn,
you can screen the libray to see which of them bind.Sequence the binding

来自主题: Biology版 - An afternoon in the library
I went the library for copying papers this afternoon. When I saw those great
names, Richard Tsien, Charles Stevens, Frank Werblin and their work in 1970s
or 1980s,I was deeply moved. It is these papers, step by step,that lead us to
understand various ion channels,and the electrophysiology of the nervous
system. Those old pieces of paper, curves, histograms and tables are still
telling vivian stories. I really admire them, not because they have a bunch of
CNS papers, or their names carved in hist

shRNA library的话,好像就Sigma和Thermo/OpenBiosystems两家有。这两家不过是
Broad和CSH这两个source的distributor,主要就是pLKO和pGIPZ两种骨架的shRNA.两种
我都用过,因为每个基因一般会order3-5个hairpin,基本上里面至少有一个的
knockdown是不错的。

biomacro, thanks for the infor.
I will not consider openbiosystem, as heard many complains about its
efficacy.
can you explain more about this
"这个library是based on pLKO hairpin shRNA。 这种shRNA比较高效"
I also worry about that for one cell, it may be infected by more than
one type of virus, making the downstream identification of specific ones
tricky?
do you think the flow based assay will be sufficient?
thanks.

测序之后alignment rate会低不少,但是我觉得不需要重做,你把library再跑一次胶

正在制作用于whole-genome sequencing的human genome library。做完ligation跑胶
看到smear,然后切下比如450-500bp的区间做PCR。但可能是50bp的interval太小或者
自己技术不好,所以最后PCR出来的亮度比较低。(当然也不排除ligation efficiency
不好)
PCR的结果如图。
还没拿去测浓度。只想问问有经验的前辈这样的情况能拿去测30 coverage的WGS吗?
另外还有一个问题,就是,我们切胶的smear每一个区间(300-400,400-500,500-600
)这些区间里都一定cover了genome的每一个部分吗?我总担心genome的有的部分没有
被涵盖到,那岂不是就人为引入了很多bias?

重复了很多次,也用commercial available的RNA重复过了
我用的RACE得到的TSS更靠3‘端,另外,我用的RACE是5'cap dependent的,所以原理
上更可能直接和translation product有关
我比较想知道cDNA library那个特别长的RNA isoform是哪来的,后来再也没人重复过
,junk product?

来自主题: Biology版 - 请教ChIP-seq做library的问题。
如果你有高浓度的PCR产物的话,可以考虑用nanodrop,或者传统的石英杯子侧浓度。
然后做serial dilution,做标准曲线。
一定要用PCR产物,质粒不可以。用质粒结果极其诡异。
我自己做的library,一般10ng/ul, 总量100-150ng,Bioanalyzer还算准确。
如果能自己用bioanalyzer最好,如果是Core做的话,一定要注意峰的面积是怎么算的
,那个分析软件有时候很crazy。

来自主题: Biology版 - Random Mutagenesis mutant library 求助
有两个问题,想请教作Random Mutagenesis 的同仁,
1. 建完mutant library后,一般需要把bacteria涂板后,然后再把平板上所有的菌落
刮下,抽提DNA,
(这一步,我能不能偷懒,直接就把transformed的bacteria接种到液体培养基里,然
后直接抽最终的bacteria DNA。)
这个问题其实就是,为何建突变文库的最后为何一定要涂板培养?
2. 还有就是,这里的细胞scraper的头太硬了,每次刮菌落时都要把培养基刮下几块,
想问大家有没有推荐一个头较软的scraper,或者对刮菌落有什么建议,谢谢,

Why do you need combine colony plasmids again as a library? Is it due to low
transformation efficiency? What strain do you use? For E. coli, B. subtilis
and yeast, your step is not necessary.

和你平时做的没啥区别 流程是一摸一样的
就是gRNA是合成oligo pool

我们都是自己建库 没啥困难的
合成oligo不贵 我们用的90k oligo大概4-5k刀的样子

单位准备买一个GC-MS library,目前的计划是要买Wiley Registry of Mass Spectral

谱库也可以quote一下价钱。搜了一下,Wiley要价$9,050.00,另外一个网站
Scientific Instrument Services (sisweb.com)要价$8050.00。那么问题来了
1.Sis这个服务商靠谱不?除了他家,还有其他靠谱的第三方可以买的吗?一般能讲到
多少%off呢
2.仪器是Agilent GC-MS,买仪器时候附带了一个Nist的,感觉版本很老,化合物谱图
收录的少而且匹配度太低。除了这个Wiley 10th之外,有其他差不多相当的图谱可以考
虑买吗?

you're right, that's common phenomenon when using iterators under different
CPUs. However, my question is not platform or cpu-dependent. I just tested
under another machine and from intel fortran to compaq. The results are the
same, 52 for i, 20 for the number of function iterations.
Is there any chance to check IMSL's library? i would like to see the source
code to find out the reason.

一群人将目前最常用的算法作成的一个library
包括了quantum monte carlo, exact diagnolization,dmrg
If you happen need to use those algorithm
this is a good one to get started.
Escpecially for people that are either doing qmc but need to
compare their result with dmrg or the oppsite.

不知道谁能够推荐一个c++ optimization的library
要求只需要提供函数值,不需要计算gradient的,然后就是要求能够有box-bound
constrained optimization。我只会用c++,所以最好是c++的库,其他的库能够用c++
调用的也行,对了,必须是multidimensi的。
其实是要optimize一个微波电路的各种参数,希望模拟出来的电路测出来的东西和实验
结果是一致的。
