Single Colony Isolation
- Observed if any colonies were made
- Could not see 3-1E
- Number of other colonies on other plates was also very small
- Mistake in protocol is inferred
- Precipitation of cells maybe at fault
- All but 3-1E was moved to new plates
PCR Reaction System
Reaction system was prepared for 3 parts, 245 uL in total
| Reagent | Amount |
|---|---|
| Autoclaved DW | 165 uL |
| 10x PCR buffer | 25 uL |
| 2 mM dNTPs | 25 uL |
| 25 mM MgSO4 | 15 uL |
| EX-F primer | 5 uL |
| PS-R primer | 5 uL |
| KOD plus Neo | 5 uL |
| Total | 245 uL |
- 49 uL of reaction solution was added to each of 4 tubes and after DNA template was added
- Length of each template is listed int the table below
| Tube | Biobrick | Length |
|---|---|---|
| 1 | 2-24G（sender） | 847 bp |
| 2 | 1-2M（RBS） | 61 bp |
| 3 | 1-23L（terminator） | 178 bp |
| 4 | 3-1E（heat sensor） | 984 bp |
- Template DNA length is calculated by adding prefix and suffix length
- Biobrick Length + Prefix length + Suffix Length
- Because Mini prep of 3-1E failed, it amplified by PCR
PCR program
| Predenature | 94℃ 2 min |
| Denature | 98℃ 10 sec |
| Extension | 68℃ 30 sec |
| Hold | 4℃ |
- 30 cycles
- KOD potency is 30 sec/kbp, so 30 sec for１cycle
Electrophoresis
- Added 1 uL of 6xSample Buffer to 5 uL of amplified DNA
- Used marker pUC1d19/Hinf1
- Added 20 uL of EtBr to 1/2 TBE
| Lane | DNA | Length of DNA |
|---|---|---|
| 1 | pUC1d19/Hinf1 | |
| 2 | 2-24G（sender） | 847 bp |
| 3 | 1-2M（RBS） | 61 bp |
| 4 | 1-23L（terminator） | 178 bp |
| 5 | 3-1E（heat sensor） | 984 bp |
