Sequences BBa_K1795008_sequence (Version 1)

Description

This sgRNA sequence was designed to target the Promoter Bba_J23106 with the N20 sequence tttacggctagctcagtcct . If this gRNA is expressed in a cell with a form of the dCas9 protein, the protein will be targeted to the N20 sequence and repress gene expression. The part is under the control of the promoter Bba_R0040. Promoter Bba_R0040 was chosen because it does not contain a PAM and therefore cannot be inadvertently repressed by dCas9 due to unintentional homology in the N20 sequence. Expression of this part can be repressed if TetR is expressed in the cell without Tetracycline present. If TetR and Tetracycline (or its analog aTc) are both present, the part will be expressed.

Notes

We made sure to use a different promoter for this part than the one which the part targets.
