目前想到的方法如下,請大家集思廣益讓「編號引子」成為正確有效又快樂之工作! 謝謝大家~

Step 1: 拉到本文下方第一則回應、看看最新一個人引子的LAB ID是用到第幾號了, 記住你要開始的號碼.
Step 2: 利用本文右下方「增加新的回應」
Step 3: 主題部分標入你login時間及大名 
Step 4: 回去你的Excel檔做編輯

**Excel檔來自生工 : (1) 在最前面加一欄 LAB ID (2) 輸入剛剛記住的號碼並完成編號 (3) copy A to G的資料 paste在ELN回應內文. (4) 記住設定table大小為700 (px) (範例見下面2015/01/01小嬿)

**Excel檔來自每得IDT : (1) 在最前面加一欄 LAB ID (2) 輸入剛剛記住的號碼並完成編號 (3) Move "Tm"、"Final nmoles"、"H2O to 100 uM"、"product bp" up to "Sequence". copy A to H的資料 paste在ELN回應內文. (4) 記住設定table大小為700 (px) (範例見下面2015/01/23 Ingrid)

建議大家自己有一個Excel檔,專門存放oligo sequences..

ps. 範例2015/01/01 小嬿那一筆的LAB ID是瞎編的,最後會刪掉; 2015/01/23 Ingrid這一筆是真的,請下一個幸運兒從978開始使用! Thanks.

Dear SF,
Only minor suggestions (in red color). Are you going to list the oncogenes screening in your proposal or we can just perform the exam?
I am current reading most recent driver mutations in the cholabgiocarcinoma, but I will be great appreciated if you can also give me the most updated/recurrent mutated genes in cholangiocarcinoma. Than I will design primers for those candidate genes.
Furthermore, I do not have a MiSeq in my lab yet, so I outsourcing now. I wish
I can get my own MiSeq machine in one year.
Kindly regards, Daw-yang

Dear Dr.Lin,
Mon, Dec 1, 2014 at 7:22 PM
Welcome to apply for TLCN samples. However, I need to tell you that many of the cholangiocarcinoma samples are not so good in the RNA quality (due to tumor necrosis), and many have low tumor %. Thus, though we have more than 150 cases, but it is impossible to get 96 cholangiocarcinoma with high tumor % and good RNA quality for your application. we probalbly can give you around 40-50 cases. If you just need DNA and tissue section, it may be possible.

Dear SF,

I can understand the RNA quality issue. We can try 48 RNA samples first to see how it goes. For DNA, it can be as much as possible, so maybe we should apply 144 DNA samples?

Dear Dr. Huang,
Thank you very much for telling us the tumor necrosis/poor RNA quality issue. With this regard, we would like to apply 48 RNA samples and associated unstained paraffin sections; and 144 DNA samples of cholangiocarcinoma tissues. A new application form with revised case numbers is attached in the mail.
Thank you very much for your great help!!

144 is too many. Please reduce to 80 to 90 cases.
Do you accept cases with a tumor percentage around 50 percent only? iPhone 
Su-Fang Lin To:  
Tue, Dec 2, 2014 at 12:25 PM
114太多啊! 真對不起,因為機器一次跑48個所以想說取它的倍數來申請...
好,那我們就申請九十例DNA檢體。另外,50% tumor cellularity 應該是OK的。謝謝妳!

You did not change the case number for DNA. Many ICC tumors have low DNA tumor %, and need to use laser capture microdissection, which will be quite expenstive (1000/ 1ug). Anyway, the total number still can not reach 144 cases. Could you reduced to 96 cases (48 wells x2) for DNA?

咦,我在昨天LOI (v3)有改成90例DNA檢體及50% tumor cellularity. 是還有地方漏掉、沒改到的嗎、還是檔案沒有附檔成功? 讓我再送一次! 麻煩您再檢查一下,不好意思。

sgRNA construction


關於CRISPR sgRNA的設計跟構築

除了委託廠商代工外

現在常用的方法

是利用外切 restriction enzyme去製造linear plasmid

再利用合成stick end 互補股引子的方式去 ligation


常用的restriction enzyme會是類似BbsI這類特別的酵素

因為他們的切點在辨識序列的外側 (5' or 3')來行成stick end

所以只要在合成primer的時後先預留正確的extra base

將回溶/reannealing/PNK 處理過的片段作ligation

就能得到sgRNA vector,

要在經定序後確認,即可得到sgRNA。


目前sgRNA的確認只能用定序的,因為塞入的片段太小(23bp),

加上sgRNA設計的時候沒有在原始被移除的序列中加上vector其他部位已經有的切位

所以需要這部,或是可以在製造linear vector的時後check 不會有 uncut vector存在


addgene提供的 空sgRNA vector 多數是用這個方法(Humanized sgRNA是例外,我被暗算過)
empty sgRNAhttp://www.addgene.org/crispr/empty-grna-vectors/

裡面也有提供類似冷泉港的單一vector。


利用這個方式建構的sgRNA成本會遠低於委託廠商代工

主要花的錢包含vector購買(NT 3000)/ primer 合成 (~50 bp per clone)/
PNK 跟 restriction enzyme  (各約莫三千元左右,可多次使用)



以下在附上我常用的sgRNA設計網站

Abstract
Chromosomal rearrangements have a central role in the pathogenesis of human cancers and often result in the expression of therapeutically actionable gene fusions. A recently discovered example is a fusion between the genes echinoderm microtubule-associated protein like 4 (EML4) and anaplastic lymphoma kinase (ALK), generated by an inversion on the short arm of chromosome 2: inv(2)(p21p23). The EML4-ALK oncogene is detected in a subset of human non-small cell lung cancers (NSCLC) and is clinically relevant because it confers sensitivity to ALK inhibitors. Despite their importance, modelling such genetic events in mice has proven challenging and requires complex manipulation of the germ line. Here we describe an efficient method to induce specific chromosomal rearrangements in vivo using viral-mediated delivery of the CRISPR/Cas9 system to somatic cells of adult animals. We apply it to generate a mouse model of Eml4-Alk-driven lung cancer. The resulting tumours invariably harbour the Eml4-Alk inversion, express the Eml4-Alk fusion gene, display histopathological and molecular features typical of ALK(+) human NSCLCs, and respond to treatment with ALK inhibitors. The general strategy described here substantially expands our ability to model human cancers in mice and potentially in other organisms.
