Self-Cleaving gRNA Kit

A fusion of BBa_K2841512 and BBa_K2841511. A self-terminating self-cleaving gRNA cis acting factor (a guide RNA without the targeting region.)

Simply put the complementary sequence of the DNA that you would like the gRNA to target just before this biobrick part, and express BBa_K2841510. The dCAS9 will localise to your target. You do not need a terminator - this part will self terminate!

Warwick 2021 Contribution

CRISPRa The handle exclusively works as a CRISPRi system. iGEM 2018 used it as a double not-gate to act as CRISPRa, needed intermediate LacI repression.

Speed By changing the handle with either of these two papers, we can make it into a CRISPRa. As per the data of the iGEM 2018 team, and per the data of the papers, we can change the induction time from days (with the not-gate system) to hours

Stability - the error bars are further away, and smaller

Flexibility - multiple gRNA spacer targets rather than just one protein, much more open in what can be enhanced.

We can compare three figures between papers to see the stability improvement. PAJ shows the original Handle, as per the page.
