Monday |
Culture overnight of transformed partsB0015-Failed B0034 –Failed J23119-Failed C0161-Failed R0062 C0170 C0171 R0079 |
The main aim of this week was to grow up any bio-bricks that may be required. Several parts failed and so had to be repeated. There are many reasons for the failure, one being the use of the wrong cells and transformations failing. |

Ligation of B0034 with C0178, C0062, E0040, C0171, C0179, C0170, C0012, C0161, E0040
|
The main aim of this week was to get our first ligations to work, however this wasn’t the case and so after the ligations were repeated and failed again, troubleshooting began. |
Tuesday |

Experiments |
Conclusion |
Monday |
No experiments were done today |
The aim of this week was to continue trying to get our first ligations to work, this wasn’t successful the digestion was found not to be complete and so this is thought to be one of the reasons behind the failed ligations. The next set of Digestions will be done overnight instead of the usual 2 hours. |

Week Beginning: 7th Sept 2009 |

|
Experiments |
Conclusion |
Monday |
PCR of Pmal to produce Ptac |
TSAP (thermo sensitive alkaline phosphatase) was used on the plasmid to dephosphorylate the plasmid so it cannot religate. Digestions with PstI were done for 8 hours and every other digestion was run for 3 hours. Ligations are now ran overnight at 4C. |
Tuesday |
Digestion of Ptac with EcoRI and XbaI and RBS with XbaL and Spel RBS was treated with SAP |
|
Wednesday |
A maxiprep was performed on the parts, which were previously cultured overnight. Digestion of the parts with Pstl to check that the parts were correct. |
|
Thursday |
PCR of C0161, C0178, C0062 which didn’t work |
|
Friday |
PCR of Gfp-LVA, which didn’t work. |
Week Beginning: 14th Sept 2009 |
||
|
Experiments |
Conclusion |
Monday |
Transformation of C0170, C0012 and pTac to RBS |
The ligations of Ptac didn’t work with the 3-hour digestion and TA cloning was inconclusive, due to a lack of resources. Parts, which were shown to be dodgy, were re-grown and checked for quality control. |
Tuesday |
Colony PCR of the ligated parts |
|
Wednesday |
Digestion of Biobricks pLux, STOP and LacI.followed by an overnight ligation of the parts |
|
Thursday |
Transformation of the ligated parts |
|
Friday |
Colony PCR of the ligated parts |
Week Beginning: 21st Sept 2009 |
||
|
Experiments |
Conclusion |
Monday |
Diluted colony PCR of the C0012-B0015, R0062-C0012. |
TA cloning was performed on Gfp-LVA to check the prefix and the suffix was digested properly. Ptac also had a successful TA cloned vector. This means that the work to check for complete digestion can begin. The main focus of this week was to finish any wiki work as this is the last week for the iGEM students. |
Tuesday |
PCR of Ptac from Pmal |
|
Wednesday |
Digestion of C0012 and C0179 |
|
Thursday |
Repeat of the previous day’s experiment followed by ligation overnight.Culture of the Gfp which was TA cloned |
|
Friday |
Maxiprep of the cultured Gfp. This failed as the DNA was sheared.
|
Week Beginning: 28th Sept 2009 |
||
|
Experiments |
Conclusion |
Monday |
Culture of the TA cloned Ptac |
The transformations failed from the beginning of the week and the conclusion of the Gfp after ligation wasn’t reached until the next week. |
Tuesday |
The Ptac and Gfp-LVA which was TA cloned was digested overnight. |
|
Wednesday |
A gel was run on the Ptac and was shown to have digested improperly. Gel purification was performed on Gfp-LVA |
|
Thursday |
Digestion of Ptac overnight and further purification of GFP-LVA. |
|
Friday |
Ligations of Ptac and Gfp-LVA with PSB1A3. |
Week Beginning: 5th Oct 2009 |
||
Experiments |
Conclusion |
|
Monday |
Digestion of Ptac with EcoRI HF and SpeI
|
Finally there was a successful ligation. The conditions, which seemed to work, were 18 hours at 16°C. Work is now going to be focussed on showing the functionality of the Ptac. |
Tuesday |
No colonies grew on the plates, suspected that the T4 Ligase was improperly killed. |
|
Wednesday |
Ligation of Ptac and GFP-LVA with PSB1A3 |
|
Thursday |
Transformations performed on the previous ligations |
|
Friday |
Colonies observed on plates. Colony PCR performed on both, GFP-LVA discovered not to work. |
Week Beginning: 12th Oct 2009 |
||
Experiments |
Conclusion |
|
Monday |
Grew up Ptac colonies, 3x Minipreps were performed. The yield was very low, so a culture for a maxiprep was then put on. |
The focus of this week was to build a construct, which could prove the functionality of the Ptac part. |
Tuesday |
Ptac was Maxiprep’d. The yield again was very low, we think this was due to the introduction of the insert causing the plasmid to become low copy. |
|
Wednesday |
Single Digestion of Ptac was performed. |
|
Thursday |
After gel purification of the Ptac, the yield was very low and so a double digestion of Ptac was performed. |
|
Friday |
Gel purification of Ptac part. |
Week Beginning: 17th Oct 2009 |
||
Experiments |
Conclusion |
|
Saturday |
Transformation of the previously ligated parts. |
The focus on this week was to continue trying to build a part, which will show functionality, and to finish off everything ready for the jamboree. |
Sunday |
Gel purification of the Ptac followed by ligation to the E0040 vector. |
|
Monday |
Cultures of a fluorescent protein were grown up with the Ptac inserted. |
|
Tuesday |
Fluorescence studies were conducted on the Ptac cultures. |
