Monday
Lac Inducible Test Assembly: Take 4, Day 4
The reporter group took the miniprep for the Plac+XylE construct to sequencing. The sequence results showed that the Plac assembled with the first 750 bp of XylE. Thus, the assembly was verified.
Insert Imperial Linker into C3 Vector, Day 2
The reporter group checked to see if the insertion of the Imperial linker into the C3 vector worked.
Assembly Step | Part Involved with Assembly Step |
---|---|
Colony PCR | Imperial linker+C3 |
Agarose Gel Electrophoresis | The colony PCR product was run on a 1% agarose gel. |
Culture | 5 ml of SOB media with 6 μl of chloramphenicol was innoculated with the Imperial linker+C3 colony. |
- Results: The gel showed a band less than 100 base pairs which matches the Imperial linker's 85 base pair length.
Extract LacZα from stock part, Day 1
The reporter group ran PCR to knock out the LacZα part from Mike's stock. The agarose gel showed that the PCR product contained the correct number of base pairs.
Tuesday
Lac Inducible Test Assembly: Take 4, Day 5
The reporter group began making stock of the Plac+XylE.
Assembly Step | Part Involved with Assembly |
---|---|
Transformation | J33204+R0010 was transformed into Escherichia coli cells. |
Culture | The SOB media and the Amp antibiotic mixture was innoculated with the transformed cells from above. The culture was left shaking overnight. |
Insert Imperial Linker into C3 Vector, Day 3
The Imperial linker+C3 culture was miniprepped and taken to sequencing. The results showed the Imperial linker with a truncated prefix (no XbaI), followed by violacein. Thus, the assembly failed.
Wednesday
Extract tev, GFP, XylE from Registry Parts, Day 1
The reporter group performed PCR to extract tev, GFP and XylE from their registry parts. The specific parts are listed below:
Gene of Interest | Registry Part | Length of Gene of Interest (bp) |
---|---|---|
K316007 | XylE | 925 |
K316007 | GFP+flag tag | 800 |
K316017 | tev protease | 720 |
Assembly Step | Part Involved with Assembly Step |
---|---|
Miniprep | K316007 K316017 |
PCR | K316007 (twice with different primers, designed May 24) K316017 |
Agarose Gel Electrophoresis | All above PCR products |
- Results: The gel showed bands all corresponding to 1000 base pairs, which is approximately correct for the genes of interest. Sequencing will further verify our PCR products.
