Because there exists a BbsI cleavage site on CMV-mcherry-pA cassette as well, it is suggested that the BbsI digested product need to be recovered directly instead of agarose gel purification.
Digest the px330-mcherry plasmid with BbsⅠ enzyme. After that, run a small amount of the digest on an agarose gel electrophoresis to check the digestion efficiency. If the px330-mcherry plasmid has been well digested, recover the remaining digestion products using a DNA purification kit (such as Tiangen, DP214-03) for restriction enzyme cleanup. In our opinion, any commonly used DNA or PCR purification kit procedure would work well, but not agarose gel purification. We do not suggest combined digestion and ligation. For all other steps (including ligation of annealed oligos into this plasmid), refer to the Zhang lab protocol for pX330-U6-Chimeric_BB-CBh-hSpCas9 (Addgene plasmid #42230).
