Coding sequence for the C-terminal section of split Cas9 nuclease.
This BioBrick was engineered to be the C-terminal domain of cas9(BBa_K2457001) coding sequence from Streptococcus pyogenes. It was designed to be an inactive domain linked with proteins like nMag (BBa_K2660008) to control to control the kinetics of activation by blue light and induce targeted genome sequence modifications (to kill or remove the recombinant DNA). This activity can be switched off simply by extinguishing the light.
This part is inserted into plasmid, and the correct construction of this recombinant plasmid was confirmed by PCR identification and sequencing of the PCR products.
Besides, the E.coli was grown in LB liquid medium, and obtain protein by heating them. The sample was electrophoresed on a sodium dodecyl sulfate(SDS)-polyacrylamide gel, followed by Coomassie blue staining.( The pictures are blurred because of the poor photographic equipment)
