Truncated CMV dCas9 Device #1

Behind a strong CMV promoter a HA-tag, a NLS and dCas9 followed by another NLS and a BGH terminator were assembled via the iGEM cloning method. The truncation of the huge dCas9 gene was performed by PCR over the backbone (=dCas9 in pSB1C3). The nucleotides between the primer pair is not amplified. One of the primers has an overlap compatible to the first bases of the other one, so that after this PCR a one fragment Gibson assembly could be performed.

Usage and Biology

This part can be used in the uniCAS Toolkit of team Freiburg as a shorter version of dCas9.

Truncation 1: here 336 bp at the 3'-end of dCas9 are missing.
