Plasmid extraction: RBS+cinR 1, RBS+HSL 1, RBS+HSL 2, RBS+HSL 3 from 5ml LB culture to 50ul EB
The concentration was measured with spectrophotometer at 260nm
- RBS+cinR 1: 8ug/ul
- RBS+HSL 1: 3ug/ul
- RBS+HSL 2: 8ug/ul
- RBS+HSL 3: 6ug/ul
Enzyme digest RBS+cinR 1
- RBS+cinR 1: 14ul
- SpeI: 1ul
- PstI 1ul
- 10x buffer 2: 2ul
- 10x BSA: 2ul
- 37°C water bath, 2h
- Heat inactivation: 65°C, 20min
Enzyme digest RBS+HSL 2
- RBS+HSL 2: 14ul
- XbaI: 1ul
- PstI: 1ul
- 10x buffer 3: 2ul
- 10x BSA: 2ul
- 37°C water bath, 2h
- Heat inactivation: 65°C, 20min
Enzyme digest RBS+HSL 3
- RBS+HSL 3: 14ul
- XbaI: 1ul
- PstI: 1ul
- 10x buffer 3: 2ul
- 10x BSA: 2ul
- 37°C water bath, 2h
- Heat inactivation: 65°C, 20min
Check RBS+cinR 1 with BsaBI digestion
- RBS+cinR 1: 3ul
- BsaBI: 1ul
- 10x buffer 2: 2ul
- H2O: 14ul
- 60°C dry bath, 1h

Well 1: 100pb ladder
Well 2 3: "RBS+HSL 2" XbaI, PstI
Well 4 5: "RBS+HSL 3" XbaI, PstI
Well 6 7: "RBS+cinR 1" SpeI, PstI
Well 8: "RBS+cinR 1" BsaBI
Comment
- There seems to be some incomplete digestion of RBS+HSL 2, possibly result from too many DNA.
- BsaBI digestion test of RBS+cinR failed. The lower bright band is probably negative supercoil form of the plasmid. Redo ligation RBS+cinR ver. 2.
- Todo: BsaBI digestion of cinR
Ligation (RBS+cinR+RBS+HSL)
- RBS+cinR: 1ul
- RBS+HSL 3: 3ul
- 10x buffer A: 1ul
- 10x ligase (Yeastern, 2U/ul): 1ul
- H2O: 4ul
- Incubated at RT for 20min
Ligation (RBS+cinR ver. 2)
- RBS: 1ul
- cinR: 1ul
- 10x buffer A: 1ul
- 10x ligase (Yeastern, 2U/ul): 1ul
- H2O: 6ul
- Incubated at RT for 20min
