Backbone
-
Vector backbonepCN50
- Backbone size w/o insert (bp) 5750
-
Modifications to backboneSite directed mutagenesis to remove BSAI site in AmpR gene. Replacement of the temperature sensitive S. aureus pT181cop-634 replicon with the wild type pT181 replicon. Vector modified to carry dead Cas9, and an sgRNA cassette. sgRNA has a GFP-expression construct cloned into its BSAI site to facilitate screening for successful cloning of targeting constructs (successful cloning events excise the GFP and colonies do not fluoresce) .
