Miniprep pSB4A5
Run PCR to amplify [http://partsregistry.org/Part:BBa_R0010 R0010], [http://partsregistry.org/Part:BBa_K123003 K123003], [http://partsregistry.org/Part:BBa_B0014 B0014] and [http://partsregistry.org/Part:BBa_PSB4A5 PSB4A5]
Run gel of PCR products
Redo PCR of [http://partsregistry.org/Part:BBa_B0014 B0014]

Results

The PCR of parts for pNT003 was successful except for the terminator (B0014), as there is no band in that lane.

from left to right: 1 ladder, 2 R0010, 3 K123000, 4 B0014 for pNT002, 5 R0040, 6 K123001, 7 B0014 for pNT003, 8 B0014 for pNT001

Transformed competent cells with pSB3C5. Ran PCR of parts for pNT001 and pNT002 Gibson assembly. Started pulsed field gel electrophoresis of some of our LA River DNA obtained by the Mo Bio kits in week 2.

Results

All of the parts for pNT001, pNT002 and B0014 were PCR'd with primers for Gibson assembly. All lanes except for lanes 4 and 5 had single bands, indicating that the parts were successfully amplified.

Retrieved and imaged pulsed field gel.
Ran PCR of R0040 and B0014 with primers that failed yesterday.
Purified PCR products for Gibson of pNT001 and pNT003.
Started overnights of pSB3C5.
Replated some pSB3C5

Results

The pulsed field gel had to be restained after running. The ladder and control appeared, but none of our LA River sample DNA. Since the ladder ranges from 5kb to 50 kb, we should be able to see some smears in the experimental lanes, as we ran a short gel last week and found that the sample DNA was greater than 10kb. Since the ladder does not seem well separated, we will try running the gel again with different parameters.

The pSB3C5 had many colonies, but none of them are red. This is strange because the plasmid contains BBa_J04450 as an insert, a RFP. We are replating on a new chlor plate and starting overnights to send off for sequencing to make sure the plasmid is okay.
We redid the PCR of R0040 and B0014, but no bands appeared in the gel.

PCR Purifications for Gibson

July 14

Miniprep overnights and send off for sequencing</br> Begin 16S sequencing</br> Redo pulse-field gel(?)</br> Do Gibson with the PCR parts that worked

Results

The minipreps of the overnight cultures all had very low concentrations of DNA.
