- Miniprep of Arac+RBS+pSB1A3
- Follow quality check
Miniprep of Arac+RBS+pSB1A3
- Transfered E.coli solution to 1.5 mL tubes, 1 mL each
- Centrifuged at 4C, 15000 rpm for 1 min
- Discarded the supernatant
- Suspended on 125 uL of Buffer P1 each
- Added 175 uL Buffer N3 each mixed by inversion
- Centrifuged at 4C, 13000 rpm for 10 min
- Transfered the supernatant to filtration column
- Centrifuged at 4C, 13000 rpm for 1 min
- Discarded the flow-through
- added 500 uL of Buffer PB to filtration column
- Centrifuged at 4C, 13000 rpm for 1 min
- Discarded the flow-through centrifuged for 1min to remove remaining buffer
- Transfered filtration column to a new 1.5 ml tube
- Resuspended on 50 ul of TE and incubated at RT for 1min
- Centrifuged at 4C, 13000 rpm for 1 min
Electrophoresis of minipreped samples
- Mixed 1 uL of sample with loading buffer 1 uL
- Added 6 uL of λ/Hind Ⅲ EcoR Marker
- Electrophoresed
Compared to marker plasmid is about 7000 bp long
Arabinose Promoter+RBS+pSB1A3 is 3455 bp long, so it might be tandem
From the picture estimate of concentration was about 30 ng/uL
plasmidとGFP+double terminatorのdigestion
以下の組成で試薬を調整した。
| Reagent | Amount |
|---|---|
| DW | 5.6 uL |
| 10x H Buffer | 1 uL |
| 0.1% BSA | 1 uL |
| Spe I | 0.2 uL |
| Pst I | 0.2 uL |
| plasmid | 2 uL |
| Total | 10 uL |
| Reagent | Amount |
|---|---|
| DW | 34 uL |
| 10x M Buffer | 5 uL |
| 0.1% BSA | 5 uL |
| Xba I | 4 uL |
| Pst I | 0.4 uL |
| GFP+double terminator | 1.6 uL |
| Total | 50 uL |
- 37C,1hour置いた。
- Mycrocon YM-10を使って切れ端の除去を行う。sampleが500 uLになるようにTEを加え、カラムに移した。
- 4C,14000g,1hour遠心した。
- 上澄みが30 uL前後残ったので、それを新しいcollection tubeに移し、カラムを逆さまにして挿入した。
- 4C,1000g,3min遠心した。
- GFP+double terminatorが30 uL、plasmid25 uL回収できたので、各1/10量の3M CH3COONaを加えた。
- 100%EtOHを回収量の2.5倍量加え、voltexにかけた。
- 4C,15000rpm,10min遠心した。
- 上澄みを捨て、70%EtOHを500 uL加え、voltexにかけた。
- 4C,15000rpm,5min遠心した。
- 上澄みを捨て、真空装置へ入れよく乾燥させた。
- 2 uLのTEで溶かした。
- -20Cで凍結保存した。
Transformation of BAC Vector
- Used DH5Alpha and MG1655 strains for electroporation
- Plated at 19:15
- Will be incubated for 18 h
