CRISPR/Cas9 antibodies

S. aureus CRISPR/Cas9 antibodies

Diagenode is pleased to offer the first antibodies directed against the CRISPR/Cas9 nuclease from Staphylococcus aureus.

S. aureus Cas9 monoclonal antibody

  • Excellent results in WB, IP and IF
  • Raised against N-terminus of Cas9 nuclease

Western blot analysis using the Diagenode monoclonal antibody directed against S. aureus Cas9
Western blot was performed on protein extracts from HEK293 cells (lane 1), HEK293 cells transfected with S. aureus Cas 9 (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.

S. aureus CRISPR/Cas9 polyclonal antibody (N-terminal)

  • Validated in WB, IF and IP
  • Raised against N-terminus of Cas9 nuclease

IF figure 1

Immunofluorescence using the Diagenode antibody directed against S. aureus CRISPR/Cas9 (N-terminal)
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. C15310260) diluted 1:1,000 in blocking solution at 4°C o/n, followed by incubation with an anti-rabbit 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.

S. aureus CRISPR/Cas9 polyclonal antibody (C-terminal)

  • Validated in WB, IF and IP
  • Raised against C-terminus of Cas9 nuclease

IP using the Diagenode antibody directed against S. aureus CRISPR/Cas9 (C-terminal)
IP was performed on whole cell extracts (200 µg) from HEK293 cells transfected with a Cas9 expression vector (lane 1 and 3), or untransfected cells (lane 2 and 4) using 1 µl of the Diagenode antibody against CRISPR/Cas9 (cat. No. C15310259). The immunoprecipitated proteins were subsequently analysed by Western blot with the monoclonal CRISPR/Cas9 antibody (C15200230). Lane 3 and 4 show the result of the IP, the input (10 µg) is shown in lane 1 and 2.
