- 1.Using [http://www.qiagen.com/products/dnacleanup/gelpcrsicleanupsystems/qiaquickgelextractionkit.aspx|QIAquick Gel Extraction Kit] and extracted DNA of pSB1C3 from the gel.
- 2.DNA bands in the agarose gel.
- After extracting DNA,I measured 5µl ,and diluted it for 20 times.
- And I measured its density.
- 3.PCR reaction was carried out by using primers designed on August 30th. The reaction conditions are summarized below.

- Ligate BBa_E0240.which doesn’t have ATG codons and pSB1C3
- I have transformed E. coli DH5 alpha with it.
- Before I made BBa_E0240.which doesn’t have ATG codons and pSB1C3.
- The densities are 19ng/µl and 25ng/µl.
- DNA samples were digested by the following restriction enzymes at 37 ℃ for 30 min.
BBa_E0240 0.5 µl pSB1C3 0.5 µl 10 x Buffer 2.5 µl F4 ligase 0.5 µl ddH2O 1.0 µl total 5 µl
- After ligate them, I have transformed E. coli DH5 alpha with it.
Results
- There aren’t any colonies on the plate.
- However I heared the success probability is very low, so next time I want to be careful about the density.

Results
- We cannot see any bands of MLF from the gel.
- So, we are effort to ligate with pSB1C3 and BBa_E0240.

- I planned to give efficiency of the ligation by giving rise to the density of GFP and vector by ethanol precipitating
Results
- I failed to rise the densities of vector and the DNA of insert.
- We lost DNA In the middle of ethanol precipitation.

アガロースゲル電気泳動
【目的】
PCRで目的のDNAが増幅しているかを調べる。
【実験方法】

" width="240px" height="280px" border="0">
PCR条件(1)の方が少しバンドが濃くなっていた。
マーカーが流れてしまった。
次回からPCR条件(1)の条件でPCRを行う。
マーカーが流れてしまったので、次回からは泳動時間を短くして電気泳動を行う。
Flag-tag dMLFの制限酵素処理
【目的】
Flag-tag dMLFのシーケンスを調べたところ、PstⅠとXbaⅠの制限酵素サイトがみられたので、Flag-tag dMLFのPCR産物が途中でPstⅠとXbaⅠによって切れてしまわないかを調べる
【実験方法】
下表に従って、3サンプル制限酵素処理を行った。
(1)
MilliQ | 6.5 µl |
Flag-tag dMLF | 20 µl |
PstⅠ | 0.5 µl |
10 x H Buffer | 3 µl |
total 30 µl |

(3)
MilliQ | 6 µl |
Flag-tag dMLF | 20 µl |

37゜Cで50分間インキュベートした後、アガロースゲル電気泳動を行った。
【結果】

" width="240px" height="280px" border="0">
Flag-tag dMLFはPstⅠとXbaⅠの制限酵素処理によって切れることはなかった。
マーカーが開ききっていなかった。
【考察】
今回の実験ではFlag-tag dMLFはPstⅠとXbaⅠの制限酵素処理によって切れることはなかったが、制限酵素処理時間が短いという可能性があるため、制限酵素処理時間を長くして再度実験を行う。
また、マーカーのラダーが開ききっていないため、泳動時間が短かったと考えられる。
次回はゲルの濃度を2倍にして電気泳動を行う。
PCR
【目的】
9/6に作製したプライマーを用いてFlag-tag dMLFを増幅させる
【実験方法】
以下の条件で4サンプルPCRを行った。
