X***h 发帖数: 74 | 4 如果我PCR后的product比较干净,能否不处理直接restriction digest? 现在我比较麻
烦的是如
果用column purification总是丢失大部分的DNA,后面digest完了还要gel
purification,
那就所剩无几了。
或者用SAP 去除primers,然后Ethanol-sodium acetate precipitation,总可以上
digestion了吧。 |

S******e 发帖数: 393 | 6 想用SalI-NheI double digetion,
NEB suggest sequential,
但我看到SalI和EcoRI double digestion 用 E.coRI buffer
NheI 和 EcoRI double digestion 也用E.coRI buffer
是不是SalI-NheI double digestion 就可以用E.coRI buffer,
而不用sequential了?
多谢回答! |

e******0 发帖数: 2149 | 7 现在在用LC/MS/MS做一个膜蛋白的定量,试过run western blots的同时做in gel
digestion 然后LCMSMS,也试过in solution digestion.听别人说过似乎in gel
digestion比in solution的效率高,但我感觉in gel technically 难做些。至今两个
方法做出来的结果差别不大。想听下前辈们的意见,哪个方法会好些。多谢! |

c***e 发帖数: 111 | 19 不知道该发哪里,就来这里求助大家了。n个月前,在Reader's Digest上Enter了一个
抽奖,结果没注意他下面有个小小的checkbox订阅他们的杂志,我没有主动uncheck,
于是就变成说我订阅了。那个抽奖只要enter就送一本免费的cooking书,我当时住学校
,因为我不想订阅杂志,那本cooking的书我根本就没收,我要求学校的宿管收件处
return了。后来也从来没有收到过任何一期杂志,第一次寄来bill我没理,12月第二次
催我要钱,说晚交有late fee,我又没理。我觉得我没有收到杂志,也没想订杂志,不
用理他。现在又发来最后一封催钱的信。警告我再不交订阅费+late fee,就要找第三
方independent collection agency来讨债。
我在杂志上留了学校的名称和自己的真名,它们一直在往我学校的宿舍地址寄,我现在
已经搬走了,我该怎么办呢。40刀钱不至于把我告上法庭吧。
查了网上说Reader‘s Digest经常莫名其妙寄东西来要钱,我怕我的支票开出去,以后
它自说自话来划钱了。而且我根本没想订杂志(虽然事实是我没有uncheck那个b... 阅读全帖 |

y****6 发帖数: 196 | 22 Thanks for sinister and kaka1000's reply. I labeled the antibody with
fluorescent dyes and quenchers, and I want to digest the antibody to small
fragments to break the FRET between dyes and quenchers. It would be best if
I can digest the antibody into the smallest fragments. Papain may not be the
best choice as it only cut antibody into three pieces. Maybe I can use some
kind of protease mixture? Any suggestion is welcome. |

m******5 发帖数: 1383 | 48 google N-chip和X-chip
两种不同的方法
用酶digest的非特异性binding少,并且因为去掉了cross linking的步骤,能用的抗体
数大大增加。缺点是很难拿到transcriptional factor和特定片断的binding 。做
Histon的人应该用得多些,但因为没有cross linking,也会引入很多非特异性的
nucleosome remodeling。
用sonication 以及cross linking配合的方法好处是拿到的相互作用理论上说更接近生
理条件,但因为引入了固定这个过程,也导致许多artificial 作用, 比如蛋白质,
DNA间非功能性的相互作用 |

另外的原因可能还有digestion enzyme的sequence preference.
说到co-IP, lysis buffer一般都加detergent吗?看别人的文章基本都加,可有的
