Transformations of the biobricks K133071, K173003 and I13453 are performed. K133071 will produce CO2 if there's pyruvate present and K173003 will produce CO2 if urea is present. I13453 is a promotor which will work if there's arabinose present.
The biobricks were transformed first into electrocometent cells and later into chemical competent cells from the strain NEb10Beta. After transformations the culture was plated on agar plates with antibiotics. The first transformations didn't work out, but the second did, because then the right competent cells were used.

Today we did a transformation with new biobricks. The biobricks were built into chemically competent cells from the strain NEb10Beta. After transformation the culture was plated on agar plates with antibiotics. The results were checked the next day.

To be able to always get the necessary biobricks, there have been made glycerolstocks of the transformed biobricks K133071, K173003 and I13453. The glycerolstocks are stored at -80 degrees Celsius. If needed, they can be retrieved from this storage to use for experiments.

To be able to always get the necessary biobricks, we made an glycerol stock after every transformation. The glycerol stocks are stored at -80 degrees Celsius. If needed, they can retrieved from this storage to use for experiments.

For further experiments there is isolated DNA needed of the biobricks J23100, K133071, K173003 and I134353. The DNA is isolated out of the bacteria with the help of a plasmid purifaction kit. After isolation this DNA can be used for digestion and ligation or other experiments. J23100 (from the glycerolstock): 325,59 ng/ul, K173003: 217,06 ng/ul, K133071: 186,79 ng/ul, I13453: 88,18 ng/ul

The biobricks J23100, K133071, K173003 and I134353 were sucessfully digested after the second time. After the digestions the biobricks K133071 and K173003 were dephosphorylated and ligated with the inserts J23100 and I13453. This was done in the original backbone of K133071 and K173003, and not another control backbone. To know if the biobricks were right ligated this was done by testing practically. See the experiments: Testing gas production.

Transformations of the biobricks (K133071 + J23100), (K13071 + I1345), (K173003 + J23100) and (K173003 + I13453) in NEB10Bèta. There was no grow except for the biobrick combination K133071 + J23100.

A colony PCR is done for the NEB10Bèta E.coli cells with expected the biobrick combination of K133071 with J23100. Nevertheless, on a gel the difference with and without promotor couldn't be seen. So there must be another way of proving the right biobricks are there.

Gasproduction testing for the biobricks (K173003 + I13453), (K133071 + I13453) and negative controls (B0015 and K133071 without urea and arabinose).
K173003 + I13453 is tested with sodiumpyruvate and arabinose for gasproduction and K133071 + I13453 is tested with urea and arabinose for gasproduction.

Digestions, gelelectrophoresis, dephosphorylations and ligations of different biobrick combinations. These biobrick combinations are 4 different promotors (J23100, I13453, K352002, K352003) with 4 different gasproduction biobricks (k173003, K173013, K133071, K133116). J23100 is about 1 kb to long. The rest seems likely to be right digested. The ligations will be transformed in NEB10bèta and digested again as control.

Transformations of the biobrick combinations in NEB10bèta. The transformations are plated on kanamycine agar plates, because all the ligations were done in pSB1K3 (kanamycine resistence) backbone. Pink and with colonies appeared after incubation by 37 degrees Celcius for about 12h. The white colonies will be used for further experiments.

Plasmid DNA was isolated of 20 different colonies. The first time something went wrong. The second time we had good concentrations of isolated plasmid DNA. After this we will digest the DNA to see if the plasmids all have the required biobricks.

Different species/tribes? of E.coli are tested as negative control. Those spacies/tribes? were: NEB10Bèta, BL21 (DE3), BL21, HB101, DH5alpha and JM109. NEB10Bèta produced the most gas. BL21, HB101 and JM101 produced none/almost none gas. Because BL21 isn't a K12 tribe? we can not use that one. That is why we will test further gasproduction in HB101 and JM109. And maybe those will be our final E.coli tribes.
