This data was developed using ab177275, the same antibody clone in a different buffer formulation.

Chromatin was prepared from HeLa cells. Cells were fixed with 1% formaldehyde for 10 minutes. ChIP was performed with 10⁷ HeLa cells and 4 µg of ab177275 [EPR17712]. ChIP DNA was sequenced on the Illumina NovaSeq 6000 to a depth of 30 million reads.

Chromatin was prepared from HeLa (Human epithelial cells from cervix adenocarcinoma) 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 ab177275 (blue), and 20µl of Anti Rabbit IgG sepharose beads. 2μg of rabbit normal IgG was added to the beads control (yellow). The immunoprecipitated DNA was quantified by real time PCR (Sybr green approach).

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab177275).

ab177275 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.

Immunofluorescent analysis of 4% paraformaldehyde-fixed, 0.1% Triton X-100 permeabilized HeLa (Human epithelial cells from cervix adenocarcinoma) cells labeling Histone H3 (acetyl K23) with ab177275 at 1/2,000 dilution, followed by Goat Anti-Rabbit IgG H&L (Alexa Fluor^® 488) (ab150077) secondary antibody at 1/1,000 dilution (green). Confocal image showing nuclear staining on HeLa cell line. Acetylation level increased after treatment with Trichostatin A (500 ng/ml) for 4 hours. The nuclear counterstain is DAPI (blue).

Tubulin is detected with  Anti-alpha Tubulin mouse MAb (ab7291) at 1/1,000 dilution followed by Goat Anti-Mouse IgG H&L (Alexa Fluor^® 594) (ab150120) secondary antibody at 1/1,000 dilution (red).

The negative controls are as follows:-
-ve control 1: ab177275 at 1/2,000 dilution, followed by Goat Anti-Mouse IgG H&L (Alexa Fluor^® 594) (ab150120) secondary antibody at 1/1,000 dilution.
-ve control 2: Anti-alpha Tubulin mouse MAb (ab7291) at 1/1,000 dilution, followed by Goat Anti-Rabbit IgG H&L (Alexa Fluor^® 488) (ab150077) secondary antibody at 1/1,000 dilution.
