Design Notes

During site-directed mutagenesis, the codons to be mutated were replaced with the most highly utilized codons in E. coli to prevent complications from the use of rare codons. The lacI IS sequences were analyzed for BioBrick restriction sites within the coding sequence to ensure their compatibility.


Source

The lacI IS mutant presented derives from the BioBrick K142046. Site-directed mutagenesis was performed by PCR, subsequent DpnI digest and transformation. The following primers were used for mutagenesis:
