- Overnight culture of I1352 grew, but no visible florescence
- Transformation Results below
| Name | Plate | Purpose | Growth Observation | |
|---|---|---|---|---|
| NEB 10 beta | LB | (+) Control shocked | lawn | |
| NEB 10 beta | LB | (+) Control | lawn | |
| NEB 10 beta | AMP | (-) Control | no growth | |
| NEB 10 beta | CM | (-) Control | no growth | |
| NEB 10 beta | CM | I1352 ligated to the backbone pSB4C5 | no growth | |
| NEB 10 beta | AMP | I1352 ligated to the backbone pSB4C5 | hundreds of colonies; some expressing RFP | |
| NEB 10 beta | AMP | I1352 ligated with itself | hundreds of colonies; some expressing RFP |
- Interpretation of Transformation Results:
- Shows the digestion/ligation process is not working
- Because the I1352 grew successfully on an AMP plate after being 'ligated' with pSB4C5, shows that the original backbone is present
- So it was not properly digested
- No growth was visible on the CM plate with the ligated I1352 with the CM resistant backbone pSB4C5
- If the digestion did not work properly, then the backbone could not be ligated with the I1352's promoter and RET
- Also, all previous stocks of BioBricks with promoters (100-107,110,113,116,0011,0040) have successfully grown on CM resistance plates, meaning they have the correct backbone, but none express RFP.
- Conclusion:
- The enzymes are bad for digestion and possibly ligation
- A new kit is being ordered
- Plans need to be made to repeat the Digestion and Ligation process with all promoters when kit arrives
