In the event that a straight-up Gibson assembly becomes desirable...

Primer strategy: to create homology between part A and part B, use >= 20 bases from the end of A and the start of B; gene A's reverse primer is the reverse complement of gene B's forward primer. It is possible to add bases in the junction. If a stop codon is needed, I only use one stop codon in case we need to use a template that completely lacks stops; in that case one stop codon will be added by the PCR.

Note that (before any PCR) the INP part has to be created by attaching linker2fs and linker2rt to BBa_K523008. Note that we must use the new, serine-rich linker to avoid certain issues.

Appendix: Sequences

Only the relevant parts of the sequence are shown; any flanking regions have not been shown, since they are irrelevant to the planning of primers. Since Gibson is scarless, the concatenation of the sequences involved is the final sequence.
