This data was developed using ab289886, the same antibody clone in a different buffer formulation.

Flow cytometric analysis of 4% paraformaldehyde fixed, 90% methanol permeabilized HeLa (Human cervix adenocarcinoma epithelial cell) cells labelling Brd4 with ab289886 at 1/500 dilution (0.1μg) (Red) compared with a Rabbit monoclonal IgG (ab172730) (Black) isotype control and an unlabelled control (cells without incubation with primary antibody and secondary antibody) (Blue). A Goat Anti-Rabbit IgG (Alexa Fluor^® 488, ab150081) at 1/2000 dilution was used as the secondary antibody.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Brd4 antibody [EPR25425-23] - BSA and Azide free (AB289893)

This data was developed using ab289886, the same antibody clone in a different buffer formulation.

Immunohistochemical analysis of paraffin-embedded Rat testis tissue labelling Brd4 with ab289886 at 1/2000 followed by a ready to use Rabbit specific IHC polymer detection kit HRP/DAB (ab209101). Nucleus staining was found in rat testis. The section was incubated with ab289886 for 30 mins at room temperature. The immunostaining was performed on a Leica Biosystems BOND^® RX instrument. Counterstained with Hematoxylin.

Secondary antibody only control : Secondary antibody is a ready to use Rabbit specific IHC polymer detection kit HRP/DAB (ab209101).

Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0, epitope retrieval solution2) for 20 mins.

Western blot - Anti-Brd4 antibody [EPR25425-23] - BSA and Azide free (AB289893)

This data was developed using ab289886, the same antibody clone in a different buffer formulation.

Western blot : Rabbit Monoclonal [EPR25425-23] to Brd4 ab289886 staining at 1/1000 dilution, shown in green; Mouse anti alpha Tubulin (ab7291) loading control staining at 1/20,000 dilution, shown in magenta. A band was observed at 200 kDa. To generate this image, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3pc Milk in TBS-0.1 % Tween^® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit 800CW & Goat anti-Mouse 680RD at 1/20,000 dilution.
