S. aureus CRISPR/Cas9 monoclonal antibody

Figure 1. Western blot analysis using the Diagenode monoclonal antibody directed against S. aureus CRISPR/ Cas9
Western blot was performed on protein extracts from HEK293 cells (lane 1), HEK293 cells transfected with S. aureus CRISPR/Cas9 (lane 2) and HeLa cells transfected with S. pyogenes Cas9 (lane 3) using the Diagenode antibody against CRISPR/Cas9 (Cat. No. C15200230), diluited 1:4,000 in PBS-T containing 3% 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 S. aureus CRISPR/Cas9
IP was performed on whole cell extracts (200 μg) from HEK293 cells transfected with a Cas9 expression vector (lane 1, 3 and 5), or untransfected cells (lane 2, 4 and 6) using 5 μg of the Diagenode antibody against CRISPR/Cas9 (Cat. No. C15200230). The immunoprecipitated proteins were subsequently analysed by Western blot. The results obtained with the Cas9 antibody are shown in lane 3 and 4. The negative control (IP with beads only) is shown in lane 5 and 6, the input (10 μg) is shown in lane 1 and 2.

Figure 3. Immunofluorescence using the Diagenode monoclonal antibody directed against S. aureus CRISPR/Cas9
Transiently transfected U2OS cells expressing SaCas9-T2A-GFP were fixed with 3.7% formaldehyde, permeabilized in 0.5% Triton-X-100 and blocked in PBS containing 2% BSA for 2 hours at RT. The cells were stained with the S. aureus CRISPR/Cas9 antibody (cat. No. C15200230) diluted 1:400 in blocking solution at 4°C o/n, followed by incubation with an anti-mouse secondary antibody coupled to DyLight594 for 1 h at RT (left figure). Nuclei were counter-stained with Hoechst 33342 (right). The middle figure shows IF with an anti-GFP antibody.
