Design Notes
For this genetic construction, we followed these summarized steps in the following image:
1) Transformation of DH5-alpha with the Green Fluorescent Protein (GFP) translational unit BBa_E0840 and with the Essential Biobrick (Regulation and transport of mercury) BBa_K1355001 that contains a bidiretional promotor regulated by the MerR protein.
2) Extraction and quantification of plasmid DNA of the BBa_E0840 and BBa_K1355001;
2) Verifying the electrophoretic profile of the extracted plasmid DNA;
Figure 1: A) Electrophoretic profile of BBa_E0840 plasmid DNA in pSB1C3; B) Eletrophoretic of BBa_K1355001 plasmid DNA in pBSK.
3) Restriction enzyme digestion of the BBa_K1355001 with SpeI and EcoRI and of BBa_E0840 with EcoRI and XbaI aiming to isolate the biobrick fragment and linearize the vector, respectively;
4) Checking the electrophoretic profile of digested samples;

5) Purification from agarose gel of the fragment (Biobrick BBa_K1355001) and the linearized vector (BBa_E0840);
4) Checking the electrophoretic profile of purified samples;
Figure 3: A) Eletrophoretic profile of BBa_E0840 (linearized vector) purified; B) Eletrophoretic profile of BBa_K1355001 (fragment) purified.
6) Ligation of the linearized vector with fragment using T4 DNA ligase;
7) Transformation of the ligation in DH5-alpha;

8) Extraction of plasmid DNA with our bioaccumulation construt from DH5-alpha transformed;
9) Check the electrophoretic profile to see results of samples linked (no fragments);

10) Restriction enzyme digestion of BBa_K1355001 + BBa_E0840 (BBa_K1355002) with EcoRI + PstI, only with EcoRI and only with PstI aiming to analyze the fragment size to be isolated (digestion with EcoRI + PstI) or the size of the linearized vector (only with EcoRI or PstI);
11) Checking the electrophoretic profile of the digested sample to obtain results showing that the isolated fragment (sample digested with EcoRI + PstI) is the junction of BBa_K1355001 + BBa_E0840 in pSB1C3 and that the linearized vector (sample digested only with EcoRI or PstI) is our biobrick in pSB1C3;
