pEcCas

pEcCas plasmid carry the cas 9 protein which can cut the target gene.

Characterization

pEcCas plasmid play an important role in our CRISPR-CAS 9 knocking out experiment.

Step1: Transformation of the pEcCas plasmid(carry cas9 protein) into E. coli AIS-0 (CICC20905). Step2: construction of the pTarget plasmid and donor DNA. Step3: transformation of pTarget plasmid and donor DNA into the AIS-0 with pEsCas inserted. Step4: Incubation of the transformed strains.
