c*********r 发帖数: 1312 | 1 我也没做过,想想就觉得不容易。RNA-seq大多数基因都有明确的boundary,很好统计
每个gene/transcript的count。但是ChIP-seq就太复杂了。是按照每个binding site在
不同条件下来比较呢?还是调节某个基因的所有binding sites来比较?后者不但要考
虑gene length,还要考虑如何定义哪些binding sites是调节哪个基因的,这个现有知
识估计还不完全吧。
简单查了一下,目前differential binding analysis(我之前叫DE其实不对),几乎
都是比较单个的binding site/peak的count差异(如果是这样的话我觉得应该不用考虑
基因长度的影响)。下边篇文章比较了十几个ChIP-seq differential analysis的软件
,简单的提到了gene ontology,找nearest gene。所以应该还是可以做GO的。里边也
提到length of differential region, 不过我就没有细看了。希望能有点帮助。

来请教一下。
我现在只有一副死沉的downhill ski,以前几次都是穿着climbing boots,然后把
downhill ski+boots背上山去滑下来。
上课再这么干估计希望不大,估计还是得买新东西。
简单看了一下,这个telemark和randonee(又称AT ski)上山的时候都是脚后跟可以抬
起来的,区别在于下山的时候telemark仍然是脚后跟可以抬起来,转弯的时候一跪一跪
的那种,而randonee可以下山的时候锁住脚跟,就跟一般的downhill ski没太大区别了
。这个理解是不是正确?
现在考虑下来,有这么几种方案,请指教。当然钱花得越少越好,穷人嘛。
1、老一套,还是象以前一样把整个downhill ski/boots啥的都背上去,这个最省钱,
啥都不用买,(可能需要snowshoe)。不过太重了,估计instructor看着也不爽。

i***r 发帖数: 1885 | 26 一般如果要在比較陡的山坡停下來,我都是選擇坐。也不太輕易解開扣子。就算解開了
,也是盡量把板子打平不讓自己滑下來
穿鞋的話還是要看不同的snowboard bindings
一小部份牌子的bindings腳後跟那塊是可以解下來平攤在地上的,我的那個就是,所以
我平時前面的bindings是固定的,要脫的話就是把後面的扣子解開。要穿的話套進去就
行了,再把後面的扣上。唯一不方便的是,既然要把後面放平,我穿還是脫都必須是要

前端框架太多太乱, 变着跟玩人似的...
Bootstrap 做 grid 排版.
JQuery 做 DOM 操作的语法糖.
因为太基本了, 用的人太多了,
所以我觉得即使以后 ES6 了,
整个 community 也能想法继续兼容它们.
有人说 ES6 以后 data binding 好了, 不需要 JQuery 这种,
作为业余前端, 我一直没搞懂,
因为 DOM操作 是比 data binding 更低级更强的抽象,
DOM操作 能实现 data binding, data binding 不能反过来实现 DOM操作. |

本质上,
Angular 是以HTML为中心看待问题,然后Javascript 用于解决逻辑问题;
React 回到了以Javascript为中心看待问题,HTML 只是用于解决界面问题。
很显然,以Javascript 为中心更符合看待问题本质,尤其对码农来说。
但是回到现实世界,HTML 这种 declarative 看问题的方式更符合人类这么多年描述事

Two Way Binding 是Angular1 年代的一个 东西。Angular2 里面本质就两种单向

Proteins and column both have charges.
Proteins can bind to the column by electrostatic interaction (so-called
non-specific binding). Of course this is not what you expect.
Assume Protein 1 is what you want, protein 2 is impurity.
If there is sodium chloride in the solution, sodium or chloride ion can
compete
with proteins to bind to column. So protein 2 will be removed from the column.
Although protein 1 is also decreased, the specific binding between histadine

then there should be highly charged part on the surface.. Protein-potein

1. 直接binding,yeast-two hybrid,或通过complex中找到。这些报道很少,一般

2. 根据已知的substrate中磷酸化位点序列的保守性来scan,推测,猜。
3. 猜:两个蛋白功能很接近,看是否直接binding,是否磷酸化。
4. 用peptide array:体外纯化的kinase,看对哪些peptide的磷酸化活性高,根据

5. 2-D胶。敲除某个kinase,看哪些蛋白的磷酸化发生变化。再质谱鉴定。
6. inhibitor array:现在有很多专门针对某个kinase的小分子inhibitor,把这些
inhibitor收齐全了,如果有某个substrate的磷酸化抗体,就用inhibitor筛一遍,看
哪个抑制强。
7. ……看我的第二篇文章:鼓吹phosphoproteomics的文章……

a*****i 发帖数: 361 | 47 我最近在做EMSA,也还是处于摸索阶段。
但是对于probe 200bp应该是可以的,我用的是400bp,因为我不太确定具体的binding
位点。另外,如果probe的条带和加蛋白以后一样只能说明没有bind的吧。我刚开始也
一直找不到binding的条带,后来配了几种不同的buffer,发现有一种效果好一点。这
个binding reaction的条件可能需要自己试一下,怎么样最合适。我用的是RNA,操作
过程中很容易降解,所以到现在也没一张我老板满意的picture。
希望你试验一切顺利! |

j***a 发帖数: 2 | 48 这里EMSA 高手很多,请大家帮忙看看
用一段PROMOTER 序列(200bp) 做probe, 能binding 到体外转录的蛋白上,但背景比
较高然后用两个片段来做probe, 有一段能binding, 。奇怪的是,当把这个片段再弄成
两段(直接合成PRIMER, ANNEAL)就没有binding了,难道是这个binding 需要二级结构
? |

b****u 发帖数: 903 | 49 在revision,review建议endogenous的coip检验是否binding,表明真实的相互作用状态,我们文章里面,overexpression可以检测到binding,但内源的试了几次,摸索了不同buffer条件没有成功,以前就看相关文献,一篇cell里面可以内源检测到该蛋白和一个底物binding,但我们没有重复出来,就连overexpression这2个蛋白,我们也没检测到binding,哎,十分frustrated啊,coip就是很tricky。 |
