Mutant PUF Expression Gel
This is our PUF protein expression gel. We decided to test the PUF protein expression under different conditions to optimize it our further experiments. Lanes labeled 2 through 7 were expressed in a higher, E. Coli standard temperature of 37 degrees C. Lanes 8 through 13 were conducted in a lower temperature of 24 degrees C. The lower temperature, as suggested by the Zefang Wang Lab at the University of North Carolina, has been confirmed to result in more specific and definite PUF protein expression in DH5a.
The parts highlighted in red are significant expressions of the wild type PUF protein.
YFP Fluorescence Data
With regards to our hypothetical results, our experimental fluorescence measurements were substantially faithful to our predictions. Looking at columns 5, 6, 7, and 8, our observations appear to be in line with what we have predicted in introducing the wild type PUF-PIN to constructs containing a control recognition site and a specific recognition site. Columns 1 and 2 are negative fluorescence controls while Columns 3 and 4 are positive fluorescence controls measured without the influence of any sort of binding site.
As a reference to our aformentioned experimental design predictions. The theoretical results chart is shown here again.
mCherry Fluorescence Data
In order to facilitate more reliable results, we also tested our constructs with the expression of an RFP, mCherry. If in the case that confounding factors influenced our results in our experiments using YFP, we could minimize inaccurate influences on our data by using a different reporter.
However, this experiment (though not as intensively compared with numerous controls as our YFP tests) has yielded unexpected results. Suggesting key differences in the gene silencing ability of PUF when used with mCherry on a Protet plasmid. Though this is not what we expected, these results are still somewhat inconclusive since we did not test the same construct on a pBAD30 plasmid instead of Protet. pBAD30 is what we used for our YFP + binding site + wild type PUF-PIN fluorescence experiments. Further experimentation is underway.
