July 30th
digestion
I tried to digest the mini-prep products again, and after Ethanol precipitation, we did electrophoresis.
transformation
I think that the E. coli which we use transformation is BL21(DE3)pLysS.
So, the E. coli could multiplication increase on LBC plate.
I'm going to do transformation , use DH5α.
Transformation of plasmid DNA ligated in 25th (pT7-RBS-Ag43-dT on pSB1K3) in E. coli(DH5α).
- Added 2ul of plasmid DNA to 50ul of thawed competent cells on ice.
- Incubated on ice for 30min.
- Added 200ul of LB then incubated the cells for 2 hours at 37C.
- Prepared and Labeled two petri dishes with LBK.
- Plate 200ul of the transformation onto first dish and spread.
- Added 450ul of LB to 50ul of the transformation and plated 200ul of it onto second dish and spread.
- Incubated the plates at 37C for 14 hours.

liquid culture
Liquid culture for pT7-RBS-Ag43-dT on pSB1K3.
- Added 2ml of LBK into culture tubes.
- Resuspended colonies.
- Incubated the tubes at 37C for
August 1st
mini-prep
mini-prep of pT7-RBS-Ag43-dT which had been cultivated from yesterday. We used FastGene Plasmid Mini Kit(Nippon Genetics) and got 50ul of DNA solutions. [[image:|thumb|mini-prep result]]
Digestion
pT7-RBS(20ng/ul) =⑨ SpeI 10xH
| DNA solution | 4.5ul |
| SpeI | 1ul |
| 10xH buffer | 1ul |
| DW | 3.5ul |
| Total | 10ul |
SpeI 10xM
| DNA solution | 4.5ul |
| SpeI | 1ul |
| 10xM buffer | 1ul |
| DW | 3.5ul |
| Total | 10ul |
pT7-RBS(30ng/ul) =⑩
SpeI 10xH
| DNA solution | 3ul |
| SpeI | 1ul |
| 10xH buffer | 1ul |
| DW | 5ul |
| Total | 10ul |
SpeI 10xM
| DNA solution | 3ul |
| SpeI | 1ul |

We couldn't cut them exactry so we cut once more time.
pT7-RBS(20ng/ul) =⑨ SpeI 10xH
| DNA solution | 4.5ul |
| SpeI | 1ul |
| 10xM buffer | 2ul |
| DW | 12.5ul |
| Total | 20ul |
Liquid culture
Liquid culture for pBAD-RBS on pSB1K3.
- Added 2ml of LBK into culture tube.
- Scraped the surface of glycerol stock of construct.
- Incubated the tube at 33C for OOhrs.
