Design Notes

A fragment of this part (linker_intein_scaffold) was synthesized by IDT as a gBlock gene fragment. This gene fragment was suffixed to the T18 domain of cyaA from Bordetella pertussis by digesting the two parts with BamHI and PstI followed by ligation.


Library

  • Choose the size of your library. Typically the length of the variable peptide loop is between 10 and 20 amino acids.
  • Dependent on the size your variable peptide loop, you can for example contruct the library as following: ATATGCGCTCGAG(NNK)xGAGCTCATTACCG (where N represent A, T, G or C and K represent G or C). The NNK codon minimizes the number of stop codons. The XhoI restriction included allows insertion of library into the scaffold.
  • Order the library as duplex-DNA
  • When delivered, cut the library and scaffold with XhoI restriction enzyme and ligate.

Important note: This part cannot be used in the standard backbones pSB1C3 or pSB1K3, as they include a xhoI restriction site. Instead we recommend using the pSB1A2 backbone
