Mutant TetRs
In vitro Main | Why TetR? | Mutant TetRs | MITOMI Data | In-vivo & In-vitro outlineHow
We used two distinct strategies to make the mutants:
- Site-specific mutagenesis , which consists of both a plasmid amplification step with forward and reverse primers containing the targeted mutation and a selection step (enzymatic digestion of the methylated dsDNA)
- PCR-induced mutagenesis : first it specifically amplifies two halves of the gene of interest from a linear template introducing mutation in one of them, than with a stich-PCR joins the halves and adds the needed extensions.
The plasmid that we used had a C-terminal eGFP fusion to the TetR and the linear template had a C-terminal His-tag. The promoters added were SP6 in the first case and the T7 in the second.
