Usage and Biology

Based on Double-gene editing expression cassette(BBa_K3402057), we designed the sgRNA that targeted at Leu site. We constructed the Pxa1, GFP, Leu editing expression cassette, and transformed it into the recombinant strain.
The transformants were cultured on solid YPD medium with hygromycin. Then the positive colonies were conducted green fluorescence observation. After that, the positive transformants without fluorescence were dotted on the Complete Medium (CM) and Minimal Medium (MM). Then the colonies grown on the CM but did not grow on the MM were the correct transformants.

The triple gene-editing efficiency was 30%.
