Western blot analysis of BCRP/ABCG2 using anti-BCRP/ABCG2 antibody (orb669055). 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 50ug of sample under reducing conditions. Lane 1: human A549 whole cell lysates, Lane 2: human MDA-MB-453 whole cell lysates, Lane 3: human HepG2 whole cell lysates, Lane 4: human Caco-2 whole cell lysates, Lane 5: human PC-3 whole cell lysates, Lane 6: rat liver tissue lysates, Lane 7: rat kidney tissue lysates, Lane 8: mouse HEPA1-6 whole cell lysates. After Electrophoresis, proteins were transferred to a Nitrocellulose membrane at 150mA 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-BCRP/ABCG2 antigen affinity purified polyclonal antibody (Catalog # orb669055) 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 1:10000 for 1.5 hour at RT. The signal is developed using an Enhanced Chemiluminescent detection (ECL) kit (Catalog # orb90503) with Tanon 5200 system. A specific band was detected for BCRP/ABCG2 at approximately 65-80KD. The expected band size for BCRP/ABCG2 is at 72KD.

IHC analysis of BCRP/ABCG2 using anti-BCRP/ABCG2 antibody (orb669055). BCRP/ABCG2 was detected in paraffin-embedded section of human mammary cancer tissue. Heat mediated antigen retrieval was performed in EDTA buffer (pH8.0, epitope retrieval solution). The tissue section was blocked with 10% goat serum. The tissue section was then incubated with 2μg/ml rabbit anti-BCRP/ABCG2 Antibody (orb669055) overnight at 4°C. Biotinylated goat anti-rabbit IgG was used as secondary antibody and incubated for 30 minutes at 37°C. The tissue section was developed using Strepavidin-Biotin-Complex (SABC) (Catalog # orb90444) with DAB as the chromogen.

Flow Cytometry analysis of SiHa cells using anti-BCRP/ABCG2 antibody (orb669055). Overlay histogram showing SiHa cells stained with orb669055 (Blue line). The cells were blocked with 10% normal goat serum. And then incubated with rabbit anti-BCRP/ABCG2 Antibody (orb669055, 1μg/1x10^6 cells) for 30 min at 20°C. DyLight®488 conjugated goat anti-rabbit IgG (5-10μg/1x10^6 cells) was used as secondary antibody for 30 minutes at 20°C. Isotype control antibody (Green line) was rabbit IgG (1μg/1x10^6) used under the same conditions. Unlabelled sample (Red line) was also used as a control.
