Validation was done using crude hybridoma supernatant. Individual optimization required.

This antibody has also been validated for use in Active Motif's enChIP kit (Catalog No. 53125).

for Cas9 antibody (mAb) (Clone 8C1-F10)Immunogen

This antibody was raised against a recombinant protein within the N-terminal region of Streptococcus pyogene Cas9. This antibody should recognize Cas9 and dCas9 based on the antigen design.

Cas9 antibody (mAb) tested by ChIP.
NIH3T3 cells stably expressing GFP-H2B, nuclease dead Cas9, and a GFP-targeting gRNA were fixed with formaldehyde, harvested and sonicated to get 200-500bp DNA fragments. 50μg chromatin was incubated over night at 4°C with the Cas9 antibody (200μl hybridoma SN, 5μg α-Flag) followed by incubation with protein G beads for 3h at 4°C. After washing chromatin was eluted from the beads and crosslinking was reversed over night at 65°C. After a proteinase K digesting step DNA was separated using phenol/chloroform/isoamyl alcohol, precipitated with ethanol/sodium acetate and dissolved in water. For the qPCR primers either targeting the GFP gene or as negative control non-targeted regions (Ppap2c +7122 and Prkcd +24069 from transcription start) were used.

HEK293 cells or HEK293 cells expressing Flag-Cas9 were lysed under native conditions. Cas9 was immunoprecipitated at 4°C from ~300μg of whole cell lysate with Cas9 clone 8C1-F10 and a 1:1 mixture of protein A and protein G sepharose. After 4x washing, the bound proteins were boiled off the beads, separated by 7.5% SDS-PAGE and transfered to nitrocellulose membranes.

Hela cells or Hela cells expressing Flag-Tagged Cas9 under the control of the PTight (Tet-ON) promoter were treated for 24h with 1 μg/μl Doxycyclin, fixed and permeabilized with Methanol/Acetone and blocked in 2% BSA in PBS for 2 hours at RT. Cells were stained with 8C1-F10 hybridoma supernatant diluted 1:10 at 4°C o/n, followed by incubation with anti mouse-AF488 coupled secondary antibody for 1 h at RT. Nuclei were counter-stained with Hoechst 33342.

Hela cells and Hela cells expressing FLAG-Tagged S.pyogenes Cas9 under the control of the PTight (Tet-ON) promoter were treated for 24h with 1μg/μl Doxycyclin and lysed under native conditions. ~30μg of whole cell lysate per lane was separated by 7.5% SDS-PAGE, transfered to nitrocellulose membrane and incubated with crude hybridoma supernatant (diluted 1:100) of Cas9 specific monoclonal antibody, 8C1-F10. All incubations were done at 4°C o/n.

for Cas9 antibody (mAb) (Clone 8C1-F10)Background

Cas9 is a nuclease from Streptococcus pyogenes that can be targeted to particular DNA sequences through a guide RNA that results in double-stranded breaks in DNA. Cas9 is part of the CRISPR/Cas9 gene-editing system that can create a DNA break at a specific location with the genome.

CRISPR (clustered regularly interspaced short palindromic repeat) is an adaptive immune system that provides protection against mobile genetic elements (viruses, transposable elements and conjugative plasmids). CRISPR clusters contain spacers, sequences complementary to antecedent mobile elements, and target invading nucleic acids. CRISPR clusters are transcribed and processed into CRISPR RNA (crRNA) Probable. In type II CRISPR systems correct processing of pre-crRNA requires a trans-encoded small RNA (tracrRNA), endogenous ribonuclease 3 (rnc) and this protein. The tracrRNA serves as a guide for ribonuclease 3-aided processing of pre-crRNA. Subsequently Cas9/crRNA/tracrRNA endonucleolytically cleaves linear or circular dsDNA target complementary to the spacer. The target strand not complementary to crRNA is first cut endonucleolytically, then trimmed by 3'-5' exonucleolytically. DNA-binding requires protein and both RNA species. Cas9 probably recognizes a short motif in the CRISPR repeat sequences (the PAM or protospacer adjacent motif) to help distinguish self versus nonself.

Chromatin IP Assays

This antibody has been validated for use in ChIP and/or ChIP-Seq, and can be used with Active Motif's ChIP-IT® High Sensitivity Kit or our magnetic bead-based ChIP-IT® Express Kits. For an overview of all of our ChIP products, please visit our Chromatin IP Page to learn about ChIP products designed for use with Cas9 antibody (mAb).

Bridging Antibody to Improve ChIP, MeDIP and IP

Some isotypes of mouse IgG antibodies do not bind well to protein G-conjugated agarose/magnetic beads, which are commonly used in ChIP, MeDIP and IP experiments. Capture efficiency can be improved by including an anti-mouse IgG bridging antibody because it binds with a strong affinity to both the protein G beads and the mouse IgG antibody. By increasing the affinity of the mouse primary antibody for the protein G bead, the Bridging Antibody for Mouse IgG can help improve the results of all ChIP, MeDIP and IP experiments that use Cas9 antibody (mAb).

Compatible Secondary Antibodies

Active Motif has developed a variety of high-quality secondary antibodies for most applications, with anti-rabbit and anti-mouse conjugates to a broad line of high-quality fluorescent molecules, as well as horse radish peroxidase (HRP). Visit our Secondary Antibody Conjugates page to find the perfect secondaries for immunofluorescence experiments with Cas9 antibody (mAb).

for Cas9 antibody (mAb) (Clone 8C1-F10)Storage

Some products may be shipped at room temperature. This will not affect their stability or performance. Upon receipt, unconjugated antibodies may be stored at -20°C for up to 2 years. Fluorophore- & enzyme-conjugated antibodies should be stored at 4°C. Fluorophore-conjugated antibodies should be protected from light. Keep reagents on ice when not in storage; to avoid repeated freeze/thaw cycles, we recommend aliquoting items that will be stored frozen into single-use fractions prior to freezing.
