5 mL of LB-Kan⁵⁰ medium were inoculated with a clone from 14.6 bearing the PheA-Arc1p-C-8x-pET28a plasmid.

As template the restriction of the sample 3.1 A1 has been used. The mutagenesis primers have been chosen together with fitting reverse primers to create fragments without the NcoI-restriction sites. These fragments should further be transformed into yeast and assembled into the whole plasmid without the restriction sites for NcoI.

Using the preculture from 14.7 60 mL of LB-Kan⁵⁰ medium were inoculated with 600 µL of the preculture and incubated at 37 °C and 220 rpm until OD₆₀₀ reached 0.5. The culture was cooled down to 18 °C and the protein production was induced with 12 µL of 500 mM IPTG. Over night the culture was incubated at 18 °C and 220 rpm. A glycerolstock of the strain containing the PheA-Arc1p-C-8x-pET28a plasmid was stored at -80 °C.

The three obtained fragments together with the NcoI-digested plasmid pMA12 have been transformed into S. cerevisiae to get the whole plasmid again. The whole procedure has been done according to the protocol.

The transformed yeast cells are incubated at RT over the easter holidays.

The cell culture from 14.8 was centrifuged (17000 rpm, 20 min, 4 °C) and the pellet resuspended in 3 mL buffer A. Lysozyme was added to a final concentration of 1 mg/mL and incubated on ice for 30 min. Afterwards the cells were lysed using ultra sound (2x 18 pulses, 30 s on ice inbetween). To clear the suspension of cell debris it was centrifuged (13000 rpm, 15 min, 4 °C). The supernatant was purified using QIAGEN Ni-NTA Spin Columns. An SDS-PAGE gel showed that the protein is produced and can be purified using Ni affinity chromatography.

60 mL LB-Kan⁵⁰ medium was inoculated from the glycerolstock prepared in 14.8 and incubated at 37 °C and 220 rpm over night.

10 x 500 mL LB-Kan⁵⁰ medium were inoculated with 5 mL of the overnight culture prepared in 14.9 and incubated at 37 °C and 220 rpm until OD₆₀₀ reached 0.5. The flasks were cooled to 18 °C and protein production was induced by adding 100 µL 500 mM IPTG. The cultures were incubated over night at 18 °C and 220 rpm. Afterwards the cells were collected by centrifugation (6000 rpm, 20 min, 4 °C), resuspended in buffer A and stored at -20 °C until further use.

Over night incubation on LB-Amp plates.

The resuspended cells from 14.10 were lysed using a french press. The lysate was incubated on ice with DNAseA and RNAseI for 10 min and centrifuged (27000 rpm, 45 min, 4 °C). The supernatant was filtered (0.45 µm) and PheA-Arc1p-C-8x purified from the cleared solution by NiNTA affinity chromatography. The combined elution fractions containing crude PheA-Arc1p-C were concentrated to a volume of 2 mL and further purified using an anion exchange column to get rid of possible tRNA contaminations. Finally the buffer was changed to dialysis buffer and the protein concentrated and stored at -80 °C in aliquods for further use.

The transformation of the E.coli cells was not successful. So it has been repeated with the rest of the prepared plasmid.

The concentration of the Hag-Flank-construct was too low (c = 5.8 ng/µL) to use it for the ligation into pMAD. A PCR has been run to increase the amount of the construct.

The PCR-product has been checked on a agarose gel (3 µL + 1 µL 6x Loading-Dye) Expected band: 2000 bp is there, but also 2 additional bands A band with the expected size of ca 2000 bp is visible but there are also two additional DNA-fragments with a lower size. The rest of the PCR-product (47 µL) has been separated on a gel and the expected DNA-fragment has been excised and purified with the Gel Extraction Kit. The purification led to a concentration of 45 ng/µL.

In order to create the circular plasmid 100 ng of the linear template were mixed with 1 µL 10x T4-Ligasebuffer, 1 µL T4-Ligase and water to give a total volume of 10 µL. This mixture was incubated for 9 h at 16 °C. The resulting plasmid was dialysed with water to decrease the salt concentration for the following transformation of E. coli Top10 electrocompetent cells with the plasmid.

Seven small colonies grew on the plate. The plate was further incubated until the afternoon. Each 6 mL LB-Amp have been inoculated with one of the colonies and incubated over night at 37 °C.

The plates from 15.12 were empty which indicates an unsuccessful ligation. A new ligation was performed after calculation with a Ligation calculator: UT Dallas

The ligation was incubated at roomtemperature for 1.5 h. Afterwards it was stored at -20 °C.

The plasmids were purified from the overnight cultures created in 14.13 using Sigma GenElute Plasmid Miniprep Kit following the included protocol. The plasmids were eluted using 45 µL water.

The plasmids were prepared and digested with ask Daniel for restriction used enzymes! Although there is a linear fragment it seems too small. The expected size of the plasmid should be 6666 bp.

The plasmids prepared on Saturday seem to be smaller as expected. For this reason a new attempt to eliminate the restriction sites was carried out. The amplification of fragment 2 (with primers iGEM 003 and iGEM 010 on 15.04.2014) did not happen without any problems such as unspecific smaller bands in addition to the expected one (ca 1000 bp). So this time primer iGEM 003 was replaced by iGEM 002 which would result in a smaller fragment of approximately 600 bp. Later on the fragments 1 and 3 together with the new created one, the digested pMa12 construct and the amyE-fragment (to overlap the region between fragments) would be transformed into S. cerevisiae for recombination.

The transformed yeast cells were incubated at 30 °C.

40 µL E. coli BL21(DE3) electrocompetent cells were transformed with 1 ng of the previously purified plasmid PheA-Arc1p-C-4x-pET28a from two different clones, incubated for 1 h at 37 °C and plated out on LB-Kan⁵⁰ plates that were incubated overnight at 37 °C.

Some new competent E. coli DH5α cells were made because the last batch of cells have not yielded in good results in the last few transformations. The cells were made according to the protocol in the method section below. To test the cells they were plated on normal LB, LB-Amp, LB-Kan and a test-trafo was carried out with pMa12 which provides an ampicillin resistance.

The transformation of E. coli DH5α with the ligation of the pMAD-vector and the hag-flank-construct was not successful. Therefore the PCR for amplification of the construct was repeated by using the hag / flank-parts or the construct itself as template.

5 mL of LB-Kan⁵⁰ medium were inoculated with a clone from 14.15 bearing the PheA-Arc1p-C-4x-pET28a plasmid.

Since the last ligation attempts were not successful the plasmid pMAD is digested by us instead using the digested pMAD from Florian. The PCR-fragments of the hag-flank-construct were purified (PCR1: c = 62 ng/µL, PCR2: c = 55 ng/µL, PCR3: c = 46 ng/µL) and digested with the enzymes BamHI and NcoI.

The restriction was incubated at 37 °C for 1 h and stored at -20 °C.

Using the preculture from 14.16 60 mL of LB-Kan⁵⁰ medium were inoculated with 600 µL of the preculture and incubated at 37 °C and 220 rpm until OD₆₀₀ reached 0.5. The culture was cooled down to 18 °C and the protein production was induced with 12 µL of 500 mM IPTG. Over night the culture was incubated at 18 °C and 220 rpm. A glycerolstock of the strain containing the PheA-Arc1p-C-4x-pET28a plasmid was stored at -80 °C.
