Gel electrophoresis of Raida's PCR products: Mal-E Gene specific primers

Chris's Gradient PCR gel electrophoresis product. The bands were more specific and showed around 400 bp, which is the size of the desired plasmid. A regular PCR and restriction digest will be run to continue to verify.

The first thing I did this morning was run a Gel Electrophoresis of my Mal-E Gene Specific Primer Testing PCR products. I ran it on a 1% gel at 100 V for an hour. Please refer to the image to the side. As it can be seen, the PCR results are positive. All the bands are near the 1200 bp band size, which indicates that it is the Mal-E gene. Furthermore, Lane 7 and Lane 13 show no band because this was the DNA that had the deleted sequence. So the fact that there is no band there is an indication of the fact that the MalE primer is functional and only amplified the MalE gene as it was supposed to. Further testing will be done to assure that the band shows the MalE Gene.

Today I ran a colony PCR of 11 of the colonies from the plates last night which was I0500-B0034 plasmid switched into pSB1AC3. Most of the colony PCRs seem to work, although the bands are faint. Primers used:

Bbk_CP_F Bbk_CP_R

These two primers anneal 100 bp upstream and downstream of the biobrick prefix and suffix. The expected size of the bands was 1400 bp which was exactly what was seen in the gel. I have decided to forward with B1,C1 which are lanes 2 and 3 respectively.

I also restreaked the two colonies on AC plates and left it in the incubator at 20 C. I also made overnight cultures of the same colonies which will be taken out of the shaker on saturday 24 July, 2010.
