J23119-gRNA (tightly target at oriC to inhibit cell replication)

It’s a gRNA sequence containing a promoter of BBa_J23119, 20bp targeting at oriC and a full-length gRNA scaffold.


Its function is proved by OD measurement after cotransformed with plasmid containing dCas9.We can observe tight repression on cell growth.



Further investigation is conducted by qPCR and flow cytometric. Its effect is even better than rapamycin, a well-used chemical molecule for replication inhibition.
