CRISPR-Cas9:The CRISPR-Cas9 gene editing system is a specific DNA modification technique for targeting genes. It combines the Cas9 protein with directed RNA, and uses the CRISPR complex to perform a precise location and cutting function, which can silence any single gene. Compared with ZFN and TALEN, CRISPR/Cas9 is easier to operate, more efficient, and can simultaneously introduce multiple mutations at different sites.

More Info:

 Quick Edit CRISPR-Cas9 Cloning Kit use pCAS9-sgRNA-puro vector construction & lentiviral vector packaging to simultaneously express spCas9, sgRNA and puromycin. It is also used for target gene knockout by cutting genomic DNA. Successful transfected / infected cells can be screened with puromycin to raise the rate of target gene knockout.

Product characteristics:

One-step to construct pCas9-sgRNA-puro vector

High positive rate

Simultaneous expression of Cas9 protein, sgRNA and puromycin

Directly used for transient experiments or lentiviral vector packaging

Storage conditions: 293T-GFP cell line stored at -80℃, the rest reagents stored at -20℃

Materials: Plasmid extraction kit, Self-provided puromycin, etc.


Brief steps:

1.  Designs gRNA and synthesis oligos;

2. sgRNA oligos anneal to form cohesive ends;

3. Linearized vector connected and transformed

4. Positive clone identification and sequencing;

5. Target gene knockout and identification;

Product advantages

1 easy to operate

2 High stability

3 Suitable for a variety of cells

4 Contain puro resistance for screening

5 Transient transfection, or lentiviral vector packaging

6 Include all major reagents
