  • Validation data

    Western blot figure 1

    Figure 1. Western blot analysis using the Diagenode monoclonal antibody directed against CRISPR/Cas9
    Western blot was performed on protein extracts from HEK293T cells transfected with Cas9 (lane 1) or from untransfected cells (lane 2) 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.

    Immunoprecipitation figure 2

    Figure 2. IP using the Diagenode monoclonal antibody directed against CRISPR/Cas9
    IP was performed on whole cell extracts from HEK293T cells transfected with a Cas9 expression vector (lane 1, 3 and 5), or untransfected cells (lane 2 and 4) using 5 µg of the Diagenode antibody against CRISPR/Cas9 (cat. No. C15200216, lane 3 and 4) or with an equal amount of IgG, used as a negative control (lane 5). The immunoprecipitated proteins were subsequently analysed by Western blot with the polyclonal Cas9 antibody (Cat. No. C15310258, diluted 1:5,000). Lane 1 and 2 show the result of the input.

    Immunofluorescence figure 1

    Figure 3. Immunofluorescence using the Diagenode monoclonal antibody directed against CRISPR/Cas9
    HEK293T cells were transiently transfected with a Cas9 expression vector. The cells were fixed with 4% formaldehyde, permeabilized in 0,1% Triton X-100 and blocked in PBS containing 5% BSA. The cells were stained with the Cas9 antibody diluted 1;400 at 4°C o/n, followed by incubation with an anti mouse secondary antibody coupled to AF596 for 1 h at RT (left). Nuclei were counter-stained with DAPI (middle). A merge of the two stainings is shown on the right.

  •  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.

    Optimization of CRISPR/Cas9 genome editing for loss-of-function in the early chick embryo
    Gandhi S. et al.
    The advent of CRISPR/Cas9 has made genome editing possible in virtually any organism, including those not previously amenable to genetic manipulations. Here, we present an optimization of CRISPR/Cas9 for application to early avian embryos with improved efficiency via a three-fold strategy. First, we employed Cas9 pr...

    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...
