... co-deliver into the cells with the Cas9/sgRNAs vector (like PX330).
For large changes (>100 bp insertions...double nickase, you could express two spacers and use PX335 to express the Cas9n (nickase).
The concept ...need to have four spacers co-expressed and using PX335 to express the Cas9n (nickase).
Tips for using homologous...nickase system is that you can express two different chimeric gRNAs with the Cas9 nickase which will together...the Cas9 nickase doesn't have the ability to induce double-stranded breaks like the wildtype Cas9 does...oligo when cloning my target spacers into the PX330 vector backbone?
A2: There is no need to add the NGG...start site to have high expression, so adding this G could help with expression, though it is possible ...
