Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to the amino terminus of histone H3 in which Lys4 is tri-methylated.
Product Usage Information
For optimal ChIP and ChIP-seq results, use 10 μl of antibody and 10 μg of chromatin (approximately 4 x 106 cells) per IP. This antibody has been validated using SimpleChIP® Enzymatic Chromatin IP Kits. The CUT&RUN dilution was determined using CUT&RUN Assay Kit #86652. The CUT&Tag dilution was determined using CUT&Tag Assay Kit #77552.

CUT&Tag was performed with HCT 116 cells and Tri-Methyl-Histone H3 (Lys4) (C42D8) Rabbit mAb, using CUT&Tag Assay Kit #77552. DNA library was prepared using CUT&Tag Dual Index Primers and PCR Master Mix for Illumina Systems #47415. The figures show binding across chromosome 12 (upper), including GAPDH (lower), a known target gene of H3K4me3 (see our ChIP-qPCR figure).

Antibody specificity was determined by Western blotting. HeLa and NIH/3T3 cell lysates were probed with Tri-Methyl Histone H3 (Lys4) (C42D8) Rabbit mAb (Panel A) or Tri-Methyl Histone H3 (Lys4) Rabbit mAb pre-adsorbed with 1.5 μM of various competitor peptides (Panels B-M). As shown, only the tri-methyl histone H3 (Lys4) peptide competed away binding of the antibody.

Anti-rabbit IgG (H+L), F(ab')2 Fragment (Alexa Fluor® 488 Conjugate) #4412 was used as a secondary antibody.
Chromatin immunoprecipitations were performed with cross-linked chromatin from HCT116 cells and Tri-Methyl-Histone H3 (Lys4) (C42D8) Rabbit mAb, using SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003. DNA Libraries were prepared using DNA Library Prep Kit for Illumina® (ChIP-seq, CUT&RUN) #56795. The figure shows binding across RPL30, a known target gene of H3K4me3 (see additional figure containing ChIP-qPCR data).
Chromatin immunoprecipitations were performed with cross-linked chromatin from HCT116 cells and Tri-Methyl-Histone H3 (Lys4) (C42D8) Rabbit mAb, using SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003. DNA Libraries were prepared using DNA Library Prep Kit for Illumina® (ChIP-seq, CUT&RUN) #56795. The figure shows binding across chromosome 8 (upper), including RPL30 (lower), a known target gene of H3K4me3 (see additional figure containing ChIP-qPCR data).
Chromatin immunoprecipitations were performed with cross-linked chromatin from HeLa cells and either Tri-Methyl-Histone H3 (Lys4) (C42D8) Rabbit mAb or Normal Rabbit IgG #2729, using SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003. The enriched DNA was quantified by real-time PCR using SimpleChIP® Human RPL30 Exon 3 Primers #7014, SimpleChIP® Human GAPDH Exon 1 Primers #5516, SimpleChIP® Human MyoD1 Exon 1 Primers #4490, and SimpleChIP® Human α Satellite Repeat Primers #4486. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one.
