The 3-Gene Inducible Plasmid: 27th - 31st August 2012 Tuesday 28th August Morning •3A assembly BBa_B0034 + WbnJ in pSB1K3 BBa_B0034 + WbnK in pSB1K3 BBa_B0034 + WfcA in pSB1K3 BBa_B0034 + WbbC(1) in pSB1K3 BBa_B0034 + WbbC(2) in pSB1K3 BBa_B0034 + WbbC(3) in pSB1K3 BBa_B0034 + WclY in pSB1K3 BBa_B0034 + WbiP in pSB1C3 BBa_B0034 + WbiP in pSB1C3 Performed with the NEB protocol with some adaptions again. The volume of digestion was changed from 50ul to 20ul by adding less water so as to increase the DNA concentration. The enzymes and buffer concentrations were adapted as below.
Afternoon •Transformation: Chloramphenicol plasmid backbone pSB1C3, 2012 Distribution Kit Plate 1 3A Tetracycline plasmid backbone pSB1T3, 2012 Distribution Kit Plate 1 7A Kanamycin plasmid backbone pSB1K3, 2012 Distribution Kit Plate 1 5A Ampicillin plasmid backbone pSB1A3, 2012 Distribution Kit Plate 1 1G Using Invitrogen TOP10 competent cells split into 2 eppendorfs containing 25μl each. Spread on the relevant antibiotic plates for each transformation using 150μls. Wednesday 29th August Morning •Gel Digest of DNA from 21/08/2012 Lanes 1, 2, 3, 4 ompA Lanes 6, 7, 8, 9 BBa_J23119 + BBa_B0034_WbnJ Lanes 10, 11 BBa_J13002 + WbnK_BBa_B0014v
Planned another 3A assembly but had run out of plasmid backbone. Afternoon •Adding cultures Cells transformed with pSB1C3, pSB1T3, pSB1K3, pSB1A3 were added into liquid medium and incubated overnight. Protocol was followed using the relevant antibiotic for the BioBrick part as the selection antibiotic. Thursday 30th August Morning •Mini-Prepping of pSB1C3, pSB1T3, pSB1K3, pSB1A3 pSB1C3, pSB1T3, pSB1K3 and pSB1A3 were nanodropped and recorded very good concentrations. Afternoon •Transformation The ligations were transformed using the Competent Cell protocol and using the Competent Cells made in the lab. •Adding cultures Cells transformed with Cyclodextrin in pSB1C3, hyaluronan synthase in pSB1C3, cyclodextrin + BBa_B0014 in pSB1C3, hyaluronan synthase + BBa_Boo14 in pSB1C3, sacB + BBa_Boo14 in pSB1C3 were added into liquid medium and incubated overnight. See, Showcasing Polysaccharide Production: 27th - 31st August 2012, Thursday 30/08/12 Protocol was followed using chloramphenicol for the BioBrick part as the selection antibiotic. Friday 31st August Morning •3A assembly BBa_J13002 + WbnJ_BBa_B0014 in pSB1K3 BBa_J13002 + WbnK_BBa_B0014 in pSB1K3 BBa_K764001+ WfcA_BBa_B0014 in pSB1A3 BBa_K764001+ WclY_BBa_B0014 in pSB1A3 BBa_K026000 + BBa_B0034 in pSB1K3 BBa_K026001 + BBa_B0034 in pSB1K3 BBa_J23119 + BBa_B0034 in pSB1K3 BBa_I0050 + BBa_B0034 in pSB1K3 BBa_B0034_WbbC obtained from PCR into pSB1C3 BBa_B0034 in pSB1A3 BBa_J13002 in pSB1A3 Performed with the NEB protocol with some adaptions again. The volume of digestion was changed from 50μl to 20μl by adding less water so as to increase the DNA concentration. The enzymes and buffer concentrations were adapted as below. This was not a Linearized Plasmid Backbone so for the plasmid digestion we used the NEB Biolabs protocol adapted to the amounts shown below.
Afternoon •Transformation The ligations were transformed using the Competent Cell protocol and using the Competent Cells made in the lab. |
