Simple Western: CRISPR-Cas9 Antibody (7A9-3A3) - N-Terminus [NBP2-36440] - Image shows a specific band for Cas9 (observed molecular weight ~158 kDa) in HeLa Cas9 lysate but not in Hela WT lysate. This experiment was performed under reducing conditions using the 12-230 kDa separation system.Immunocytochemistry/ Immunofluorescence: CRISPR-Cas9 Antibody (7A9-3A3) - N-Terminus - BSA Free [NBP2-36440]
Immunocytochemistry/Immunofluorescence: CRISPR-Cas9 Antibody (7A9-3A3) - N-Terminus [NBP2-36440] - Hela cells were transiently transfected with an N-terminally Flag-tagged S. pyogenes Cas9 expression vector. The cells were stained with the Cas9 antibody followed by anti mouse-AF488 coupled secondary antibody. Nuclei were counter-stained with Hoechst 33342.Immunoprecipitation: CRISPR-Cas9 Antibody (7A9-3A3) - N-Terminus - BSA Free [NBP2-36440]
Immunoprecipitation: CRISPR-Cas9 Antibody (7A9-3A3) - N-Terminus [NBP2-36440] - HEK293T expressing N-terminally Flag-tagged S.pyogenes Cas9 were lysed 72h post transfection by resuspending the cells in Hunt buffer and subjecting to 3 freeze-thaw cycles in liquid nitrogen/ice. Proteins were immunoprecipitated from 100ug of whole cell lysate for 1h at 4C with Cas9 supernatant followed by incubation for 1h at 4C with a 1:1 mixture of protein A/G sepharose beads, or for 2h at 4C with Cas9 ab crosslinked to a 1:1 mixture of protein A/G sepharose beads. Beads were washed 2x with Hunt buffer and 1x with TBS. Bound proteins were eluted by boiling in Laemmli, separated by SDS-PAGE and transferred to nitrocellulose. Membrane was blocked, incubated with Cas9 ab, incubated with HRP anti-mouse secondary. *IgG heavy chainApplications for CRISPR-Cas9 Antibody (7A9-3A3) - N-Terminus - BSA Free

Background: CRISPR-Cas9
Using CRISPR-Cas9 technology, double-stranded DNA breaks may be induced within specific targeted genome sequences (target DNA; protospacer) for insertion or removal of DNA sequences for gene editing applications. To target a specific loci, a gRNA that will bind to a specific target sequence of DNA within a genome is created. The gRNA will recognize the DNA sequence, and the Cas9 enzyme will cleave the DNA at the targeted location. Once the targeted DNA is removed by Cas9, the cell's own DNA repair mechanism is used to insert or remove a DNA sequence for genomic editing.
Cas9 detection is used to confirm and evaluate CRISPR Cas9 gRNA transfection efficiency. Western blot analysis of CRISPR-Cas9 gRNA transfected cell lysates with Cas9 antibodies identifies the protein having a theoretical molecular weight of 160kDa. Broad areas of research are benefiting from CRISPR-Cas9 based gene editing tools including studies of basic immunity functions, genetic screening and disease treatment (2). Ethical concerns have led to many countries making it illegal to manipulate human germline cells or perform embryo genome editing.
