When constructing our BioBricks, we made use of the IDT synthesis offer. This way we were able to generate our required parts in a fast and efficient way. Additionally, we made use of PCR amplification with our constructed expression plasmids as template to construct several BioBricks. All of the parts contain a coding sequence, some of which extended with promoters or introns. Since our fusion protein <a href="http://parts.igem.org/Part:BBa_K2643000" class="grnbl" target="_blank">BBa_K2643000</a> consists of the dxCas9, linker and Tn5 coding sequences this part is registered as composite part. The basic parts comprising the our fusion protein composite part are documented separately and also exist as separate BioBricks. This is advantageous for those wishing to combine one of our basic parts with a different expression level or compose a different composite part altogether. These basic parts were generated by using PCR on the composite part and restriction ligation cloning. We created a part collection comprised of 6 basic parts encoding for different EPO coding sequences, 2 basic parts encoding for the required components for targeted sequencing and 1 composite part: our fusion protein. All BioBricks are submitted with elaborate characterisation so the user may choose the best protein for their project accordingly. Our favourite basic part is <a href="http://parts.igem.org/Part:BBa_K2643001" class="grnbl" target="_blank">BBa_K2643001</a> and our favourite composite part is <a href="http://parts.igem.org/Part:BBa_K2643000" class="grnbl" target="_blank">BBa_K2643000</a>.
