Plasmids used during the characterization of our biobrick

Figure x. Plasmids used in our experiments. pSub. can be either of mNG-Aß1-42, EGFP-Aß1-42, a-synuclein-EGFP and Tau0N4R-EGFP. As seen in the next figure, four combinations were introduced into E.coli (BL21). Substrate, substrate and GroES, substrate and GroES and GroE, substrate and GroE.

Overview of our experimental design to archive the results shown below

Figure x. A simple explaination on how we archived our experimental results. The plasmids shown is the same as before, where A can be either of mNG-Aß1-42, EGFP-Aß1-42, a-synuclein-EGFP and Tau0N4R-EGFP, B is always pGroE7 and C is pSB4A5-GroES. The concentrations used for inducing the chaperone plasmids was 0.25 mg/ml L-arabinose, 200 ng/ml tetracycline. For the substrate plasmids we used 0.5 mM IPTG, and the substrate was induced 30 mins after the chaperone plasmids.

Results from the experimental measurements is shown below. The y-axis represent the fluorescence intensity at 520 nm. The excitation was done at 485 nm. The x-axis show the time for the measurements. The second set of graphs shown for each substrate represent the normalized values for the fluorescence intensity. This was analyzed because it represent the kinetic growth of the substrate proteins. As seen in the those graphs, the 50 % of max has been marked out as a dotted line. This makes it easy to interpret if the folding of the different substrate proteins was affected by the chaperone systems.
