+ | <b>Short description of our work, our results and our supporters</b> | ||
+ | |||
+ | |||
+ | The creation of certain constructs was necessary for our two systems for cell selection by means of apoptosis: “Cut’N’Survive” and “Jump-Or-Die”. We searched for sources of the DNA sequences we needed and found several supporters which are listed below. | ||
+ | |||
+ | Most genes and promoters were amplificated via PCR with overhang-primers with the BioBrick prefix or suffix. If the sequence contained a EcoR1-, Pst1-, Xba1-, Spe1- or Not1- restriction site, we used mutagenesis primers and fusioned both DNA parts by fusion PCR. All PCRs worked out, even the fusion PCRs. | ||
+ | |||
+ | The length of the PCR products were tested by agarose gel electrophoresis. We tried to sequence our PCR products, but obtained poor results and resorted to sequencing the plasmids. | ||
+ | |||
+ | In parallel, we made competent cells and multiplied ccdB (death gene)-vectors with different antibiotic resistances. All components were digested with the appropriate restriction enzymes. The samples were cleaned with a PCR clean up kit or dephosphorylated to reduce false ligations. | ||
+ | |||
+ | We ligated our constructs and several interim stages with the 3A-assembly according to our schedule. The ligations were transformed to E.coli DH5α strains and selected by antibiotics. Afterwards, some colonies were picked and we tested the insertion of the construct by colony PCR. | ||
+ | |||
+ | If the colony PCR resulted in bands of the right size, we extracted the plasmids from overnight cultures and sequenced the samples with forward and reverse BioBrick primers. | ||
+ | |||
+ | Unfortunately, not all BioBricks were cloned succesfully. However, we were able to produce 4 BioBricks, one of which represents a full construct while the other three are intermediates. The system wasn't completed on time, so we weren´t able to test them in eukarytic cell lines. | ||
+ | |||
+ | |||
+ | |||

Short description of our work, our results and our supporters
Most genes and promoters were amplificated via PCR with overhang-primers with the BioBrick prefix or suffix. If the sequence contained a EcoR1-, Pst1-, Xba1-, Spe1- or Not1- restriction site, we used mutagenesis primers and fusioned both DNA parts by fusion PCR. All PCRs worked out, even the fusion PCRs.
The length of the PCR products were tested by agarose gel electrophoresis. We tried to sequence our PCR products, but obtained poor results and resorted to sequencing the plasmids.
In parallel, we made competent cells and multiplied ccdB (death gene)-vectors with different antibiotic resistances. All components were digested with the appropriate restriction enzymes. The samples were cleaned with a PCR clean up kit or dephosphorylated to reduce false ligations.
We ligated our constructs and several interim stages with the 3A-assembly according to our schedule. The ligations were transformed to E.coli DH5α strains and selected by antibiotics. Afterwards, some colonies were picked and we tested the insertion of the construct by colony PCR.
If the colony PCR resulted in bands of the right size, we extracted the plasmids from overnight cultures and sequenced the samples with forward and reverse BioBrick primers.
Unfortunately, not all BioBricks were cloned succesfully. However, we were able to produce 4 BioBricks, one of which represents a full construct while the other three are intermediates. The system wasn't completed on time, so we weren´t able to test them in eukarytic cell lines.
The protocols we used are listed here: Protocols
These Biobricks we submitted:

What we did
The creation of certain constructs was necessary for our two systems for cell selection by means of apoptosis: “Cut’N’Survive” and “Jump-Or-Die”. We searched for sources of the DNA sequences we needed and found several supporters which are listed below.
