    Figure 1. Western blot analysis using the Diagenode monoclonal antibody directed against CRISPR/Cas9
    Western blot was performed on protein extracts from HeLa cells transfected with Cas9 (lane 2) or from untransfected cells (lane 1) using the Diagenode antibody against CRISPR/Cas9 (Cat. No. C15200216), diluted 1:5,000 in PBS-T containing 0.5% NFDM. The marker is shown on the left, position of the Cas9 protein is indicated on the right.

    Figure 2. IP using the Diagenode monoclonal antibody directed against Cas9
    IP was performed on whole cell extracts (300 μg) from HeLa cells transfected with a Cas9 expression vector (lane 1 and 3), or untransfected cells (lane 2 and 4) using 5 μg of the Diagenode antibody against Cas9 (Cat. No. C15200216). The immunoprecipitated proteins were subsequently analysed by Western blot with the polyclonal Cas9 antibody (Cat. No. C15310258, diluted 1:5,000). Lane 3 and 4 show the result of the IP, the input (15 μg) is shown in lane 1 and 2.

    Immunofluorescence figure 1

    Figure 3. Immunofluorescence using the Diagenode monoclonal antibody directed against CRISPR/Cas9
    Hela cells were transiently transfected with a Cas9 expression vector. The cells were fixed with methanol/acetone and blocked in PBS containing 2% BSA. The cells were stained with the Cas9 antibody diluted 1;400, followed by incubation with an anti mouse secondary antibody coupled to AF488 for 1 h at RT (left). Nuclei were counter-stained with Hoechst 33342 (right).

  • Background

    CRISPR systems are adaptable immune mechanisms which are present in many bacteria to protect themselves from foreign nucleic acids, such as viruses, transposable elements or plasmids. Recently, the CRISPR/Cas9 (CRISPR-associated protein 9 nuclease, UniProtKB/Swiss-Prot entry Q99ZW2) system from S. pyogenes has been adapted for inducing sequence-specific double stranded breaks and targeted genome editing. This system is unique and flexible due to its dependence on RNA as the moiety that targets the nuclease to a desired DNA sequence and can be used to induce indel mutations, specific sequence replacements or insertions and large deletions or genomic rearrangements at any desired location in the genome. In addition, Cas9 can also be used to mediate upregulation of specific endogenous genes or to alter histone modifications or DNA methylation.

  • Testimonials

    When doing CRISPR experiments, it is essential to verify the expression levels of the Cas9 to ensure high-quality results. Diagenode's new CRISPR/Cas9 4G10 antibody is extremely specific, able to recognize different Cas9 fusion proteins (even those used for CRISPRi experiments) and compatible with many biochemical assays, such as immunofluorescence, western blot and immunoprecipitation. Among the different antibodies in the market, Diagenode's 4G10 CRISPR/Cas9 is our antibody of choice.

    Enhanced CRISPR/Cas9-mediated precise genome editing by improved design and delivery of gRNA, Cas9 nuclease, and donor DNA
    Liang W. et al.
    While CRISPR-based gene knock out in mammalian cells has proven to be very efficient, precise insertion of genetic elements via the cellular homology directed repair (HDR) pathway remains a rate-limiting step to seamless genome editing. Under the conditions described here, we achieved up to 56% targeted integration ...

    CRISPR-Mediated Gene Targeting of Human Induced Pluripotent Stem Cells
    Susan M. Byrne, George M. Church
    CRISPR/Cas9 nuclease systems can create double-stranded DNA breaks at specific sequences to efficiently and precisely disrupt, excise, mutate, insert, or replace genes. However, human embryonic stem cells and induced pluripotent stem cells (iPSCs) are more difficult to transfect and less resilient to DNA damage than...
