Description:

Cloning vector for Streptococcus pyogenes Cas9 (SpCas9) single guide RNA transcription, controlled by the U6 snRNA promoter #4 (3' of Cre15.g640800). The 20 bp target site can be inserted in a cut-ligation reaction as annealed oligos into an Esp3I cloning site. The immediate 4-bp sequence upstream of the transcriptional start site was changed to ACTT in all U6 constructs to simplify the cloning procedures.

Bacterial Host Strain:
