cI Repressor Test Assembly, Day 23
The sensor group continued their assembly of their testing construct. They placed an RBS in the K3 vector with Cro, the OR in front of the mCherry reporter, terminator, cI repressor and J23113 promoter as well as in front of the 34mCherry. Finally, the sensor group attempted (again) to put the B0032 RBS in front of the cI repressor.
Protocol | Part Involved with Protocol | |
---|---|---|
Restriction Digest | Inserts using XbaI and PstI: | 34mCherry K648000+K648001 |
Inserts using EcoRI and SpeI: | B0032 B0034 | |
Vectors using EcoRI and XbaI: | C0051 K3+Cro | |
Vector using SpeI and PstI: | K3+OR | |
Ligation | B0034 + K3 + Cro KOR + K648000 + K648001 KOR + 34mcherry B0032 + C0051 | |
Transformation/Plating | The above ligations were transformed into Escherichia coli cells and plated on kanamycin and ampicillin resistant plates. |
The sensor group also transformed K3+Cro and J23113+B0031+C0051 in order to make stocks. The B0034+C0051 was grown up from stock.

cI Repressor Test Assembly, Day 24
The sensor group verified their assemblies from 6/28. Colonies containing KOR + 34mcherry, B0034 + K3 + Cro, KOr + K648000+K648001 were amplified through colony PCR. Agarose gel electrophoresis showed that these assemblies seemed to work. The colonies were grown up in culture so the plasmids can be extracted and sent to the sequencing center tomorrow morning.
The B0034 and B0034+C0051 plasmids were extracted using the Omega-Biotek miniprep protocol. These plasmids will be used at a later date.

cI Repressor Test Assembly, Day 25
The following constructs made on 6/28 were sent to sequencing.
KOr + 34mcherry
B0034 + K3 + Cro
KOr + K648000 + K648001
The results showed that these colonies were just vector background. As a result, these assemblies must be done again.
The sensor group also assembled a constitutive promoter to two RBS+cI repressor part. Also, the KOR part was placed in front of the mCherry+terminator part.

Transformation/Plating | The above ligations were transformed into Escherichia coli cells and plated on kanamycin and ampicillin resistant plates. |
The cI repressor (C0051) plasmid was transformed into Escherichia coli cells from the registry kit plate.
The following constructs were sent to sequencing:
Construct | Sequencing Result |
---|---|
J23113 + B0032 + C0051 | good |
J23113 + B0033 + C0051 | bad |
KOr + K648000 | good |

The sensor group tried attaching the cI repressor to two different RBS.
