Part Characterization: Using PCR reaction, we amplified part of the plasmid, excluding part of the mRFP and RBS. This enabled us to insert the gblocks into the plasmid which included already the appropriate backbone and overlaps for the assembly.
The gblock was inserted using Gibson Assembly. Before the assembly, we have done DPN1 to ensure no unwanted DNA template was present and used PCR clean kit to prepare the amplified backbone. Then we proceeded to the Gibson reaction and transformed the resulting plasmid into E. coli DH10beta. -DH10beta containing non fluorescent plasmid for negative control. -DH10beta containing the original part. -DH10beta containing this part. - We included also 3 samples of pure LB in order to use it as blank. Because RFP can absorb light at 600nm and lead to false measurements, concentration of bacteria was estimated using OD700 as recommended previously by the iGEM committee . For measuring the protein's fluorescence, we used excitation wavelength of 540 nm and emission wavelength of 650 nm. Calculation of the fluorescence intensity: Individual Intensity= (Florescence of plasmid - florescence of LB) / # Colonies in OD700 Then, for each type of bacteria, we calculated the average of the three appropriate samples intensity.
The intensity of our improvment was almost 3 times stronger than the original part. |
