Lab work

Ordered DNA

The transformations of 19 July containing the different ligations gave colonies (~5 per plate). We picked 5 colonies per plate and performed a colony PCR.

Alkane degradation

Unfortunately there were no transformants on yesterday's plates. This is most likely due to the fact that the ligation didn't work with the small pieces of DNA of the RBSs. Next plan is to cut open the RBS plasmid without removing the RBS (with SpeI and PstI) and insert the gene in this plasmid. We will try this tomorrow.

Emulsifier

2% agarose of colony PCR. Gel runned at 100V for 1 hour. Of all samples 10 μL + 2 μL loadingbuffer was loaded. 5 μL was loaded of marker
There were small colonies on the plates. Pieter picked seven and performed colony PCR on them.

2 Transformant #1 of ligation mix R0011-B0032 300 G00100 + G00101 ✗
3 Transformant #2 of ligation mix R0011-B0032 300 G00100 + G00101 ✗
4 Transformant #3 of ligation mix R0011-B0032 300 G00100 + G00101 ✗
5 Transformant #4 of ligation mix R0011-B0032 300 G00100 + G00101 ✗
6 Transformant #5 of ligation mix R0011-B0032 300 G00100 + G00101 ✗
7 Transformant #6 of ligation mix R0011-B0032 300 G00100 + G00101 ✗
8 Transformant #7 of ligation mix R0011-B0032 300 G00100 + G00101 ✗

Unfortunately all other lanes were empty or the same as the negative control. So from this gel we conclude that the ligation has failed.
