Recombinant Anti-Histone H3 (tri methyl K9) antibody [EPR16601] - ChIP Grade – BSA and Azide free (ab232324)

CUT&RUN was performed using the ChIC/CUT&RUN pAG-MNAse ab285373, 10⁵ HeLa cells and 2µg of ab176916 [EPR16601]. The resulting DNA was sequenced on the Illumina NovaSeq 6000 to a depth of 10 million reads. The ChIP data was conducted on chromatin prepared from HeLa cells. Cells were fixed with 1% formaldehyde for 10 minutes. ChIP was performed with 10⁷ HeLa cells and 4 µg of ab176916 [EPR16601]. ChIP DNA was sequenced on the Illumina NovaSeq 6000 to a depth of 30 million reads.

Chromatin was prepared from HeLa cells according to the Abcam X-ChIP protocol. Cells were fixed with formaldehyde for 10 minutes. The ChIP was performed with 25µg of chromatin, 2µg of ab176916 (blue), and 20µl of Protein A/G sepharose beads. No antibody was added to the beads control (yellow). The immunoprecipitated DNA was quantified by real time PCR (Taqman approach for active and inactive loci, Sybr green approach for heterochromatic loci). Primers and probes are located in the first kb of the transcribed region.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab176916).

ab176916 was tested in Peptide array against 501 different modified and unmodified histone peptides; each peptide is printed on the array at six concentrations (each in triplicate).
 
Circle area represents affinity between the antibody and a peptide: all antigen-containing peptides are displayed as red circles, all other peptides as blue circles. The affinity is calculated as area under curve when antibody binding values are plotted against the corresponding peptide concentration. Each circle area is normalized to the peptide with the strongest affinity.
