Please see the Schier lab website http://labs.mcb.harvard.edu/schier/ for detailed protocols about target site selection, sgRNA production, stop codon cassette design, Cas9 protein purification, injection and downstream analysis.
This plasmid was used to express a His-tagged Cas9 protein in E. coli and purify it by nickel-based affinity purification.The Cas9 protein and sgRNA were incubated at room temperature to form the Cas9 protein/sgRNA complex in vitro, which was then microinjected into zebrafish zygotes. See publication for more details.
These plasmids were created by your colleagues. Please acknowledge the Principal Investigator, cite the article in which the plasmids were described, and include Addgene in the Materials and Methods of your future publications.
