Anti-BRD2 Antibody Picoband®

I-BET151 reduces Brd4 levels in the kidney of HN rats. (A) A rat model of HN was established and treated with I-BET151 as indicated in “Material and Methods.” After 3 weeks, kidneys were taken for immunoblot analysis for Brd2, Brd3, Brd4 or GAPDH. Expression levels of Brd2 (B) , Brd3 (C) , Brd4 (D) were quantified by densitometry analysis and then normalized with GAPDH. (E) Photomicrographs (original magnification, ×400) illustrate immunohistochemical Brd4 staining of kidney tissues. (F) Brd4 staining graphic presentation of quantitative data. Data are represented as the mean ± SEM. * p < 0.05; ** p < 0.01.

Flow Cytometry analysis of 293T cells using anti-BRD2 antibody (A02412-1).
Overlay histogram showing 293T cells stained with A02412-1 (Blue line). To facilitate intracellular staining, cells were fixed with 4% paraformaldehyde and permeabilized with permeabilization buffer. The cells were blocked with 10% normal goat serum. And then incubated with rabbit anti-BRD2 Antibody (A02412-1, 1 μg/1x10⁶ cells) for 30 min at 20°C. DyLight®488 conjugated goat anti-rabbit IgG (BA1127, 5-10 μg/1x10⁶ cells) was used as secondary antibody for 30 minutes at 20°C. Isotype control antibody (Green line) was rabbit IgG (1 μg/1x10⁶) used under the same conditions. Unlabelled sample without incubation with primary antibody and secondary antibody (Red line) was used as a blank control.

Western blot analysis of BRD2 using anti-BRD2 antibody (A02412-1).
Electrophoresis was performed on a 5-20% SDS-PAGE gel at 70V (Stacking gel) / 90V (Resolving gel) for 2-3 hours. The sample well of each lane was loaded with 30 ug of sample under reducing conditions.
Lane 1: human Hela whole cell lysates,
Lane 2: human A431 whole cell lysates,
Lane 3: human Jurkat whole cell lysates,
Lane 4: human 293T whole cell lysates.
After electrophoresis, proteins were transferred to a nitrocellulose membrane at 150 mA for 50-90 minutes. Blocked the membrane with 5% non-fat milk/TBS for 1.5 hour at RT. The membrane was incubated with rabbit anti-BRD2 antigen affinity purified polyclonal antibody (Catalog # A02412-1) at 0.5 μg/mL overnight at 4°C, then washed with TBS-0.1%Tween 3 times with 5 minutes each and probed with a goat anti-rabbit IgG-HRP secondary antibody at a dilution of 1:5000 for 1.5 hour at RT. The signal is developed using an Enhanced Chemiluminescent detection (ECL) kit (Catalog # EK1002) with Tanon 5200 system. A specific band was detected for BRD2 at approximately 110 kDa. The expected band size for BRD2 is at 88 kDa.

IF analysis of BRD2 and Tubulin beta using anti-BRD2 antibody (A02412-1) and anti-Tubulin beta antibody (M05613-4).
BRD2 and Tubulin beta was detected in an immunocytochemical section of A431 cells. Enzyme antigen retrieval was performed using IHC enzyme antigen retrieval reagent (AR0022) for 15 mins. The cells were blocked with 10% goat serum. And then incubated with 5 μg/mL rabbit anti-BRD2 Antibody (A02412-1) and mouse anti-Tubulin beta Antibody (M05613-4) overnight at 4°C. DyLight®488 Conjugated Goat Anti-Rabbit IgG (BA1127) and DyLight®594 Conjugated Goat Anti-Mouse IgG (BA1141) were used as secondary antibody at 1:100 dilution and incubated for 30 minutes at 37°C. Visualize using a fluorescence microscope and filter sets appropriate for the label used.
