Western blot analysis of PAR-3/PARD3 using anti-PAR-3/PARD3 antibody (orb865445). 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 MCF-7 whole cell lysates, Lane 2: human HEK293 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. 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-PAR-3/PARD3 antigen affinity purified polyclonal antibody (Catalog # orb865445) 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 # orb90503) with Tanon 5200 system. A specific band was detected for PAR-3/PARD3 at approximately 151 kDa. The expected band size for PAR-3/PARD3 is at 151 kDa.

IHC analysis of PAR-3/PARD3 using anti-PAR-3/PARD3 antibody (orb865445). PAR-3/PARD3 was detected in a paraffin-embedded section of human appendiceal adenocarcinoma tissue. Heat mediated antigen retrieval was performed in EDTA buffer (pH 8.0, epitope retrieval solution). The tissue section was blocked with 10% goat serum. The tissue section was then incubated with 2 μg/ml rabbit anti-PAR-3/PARD3 Antibody (orb865445) 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.

IHC analysis of PAR-3/PARD3 using anti-PAR-3/PARD3 antibody (orb865445). PAR-3/PARD3 was detected in a paraffin-embedded section of human laryngeal squamous cell carcinomatissue. Heat mediated antigen retrieval was performed in EDTA buffer (pH 8.0, epitope retrieval solution). The tissue section was blocked with 10% goat serum. The tissue section was then incubated with 2 μg/ml rabbit anti-PAR-3/PARD3 Antibody (orb865445) 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.

IF analysis of PAR-3/PARD3 using anti-PAR-3/PARD3 antibody (orb865445). PAR-3/PARD3 was detected in an immunocytochemical section of U20S cells. Enzyme antigen retrieval was performed using IHC enzyme antigen retrieval reagent (orb90553) for 15 mins. The cells were blocked with 10% goat serum. And then incubated with 5 μg/mL rabbit anti-PAR-3/PARD3 Antibody (orb865445) overnight at 4°C. DyLight®488 Conjugated Goat Anti-Rabbit IgG was used as secondary antibody at 1:100 dilution and incubated for 30 minutes at 37°C. The section was counterstained with DAPI. Visualize using a fluorescence microscope and filter sets appropriate for the label used.

Flow Cytometry analysis of HepG2 cells using anti-PAR-3/PARD3 antibody (orb865445). Overlay histogram showing HepG2 cells stained with orb865445 (Blue line). The cells were blocked with 10% normal goat serum. And then incubated with rabbit anti-PAR-3/PARD3 Antibody (orb865445, 1 μg/1x10^6 cells) for 30 min at 20°C. DyLight®488 conjugated goat anti-rabbit IgG (5-10 μg/1x10^6 cells) was used as secondary antibody for 30 minutes at 20°C. Isotype control antibody (Green line) was rabbit IgG (1 μg/1x10^6) used under the same conditions. Unlabelled sample (Red line) was also used as a control.
