Western blot analysis of PP2A-alpha/PPP2CA using anti-PP2A-alpha/PPP2CA antibody (orb654389). 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 HELA whole cell lysates, Lane 2: human HEPG2 whole cell lysates, Lane 3: monkey COS-7 whole cell lysates, Lane 4: rat PC-12 whole cell lysates, Lane 5: mouse NIH/3T3 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 mouse anti-PP2A-alpha/PPP2CA antigen affinity purified monoclonal antibody (Catalog # orb654389) 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-mouse 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 # orb90502) with Tanon 5200 system. A specific band was detected for PP2A-alpha/PPP2CA at approximately 36KD. The expected band size for PP2A-alpha/PPP2CA is at 36KD.

IF analysis of PP2A-alpha/PPP2CA using anti-PP2A-alpha/PPP2CA antibody (orb654389). PP2A-alpha/PPP2CA was detected in immunocytochemical section of HELA 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 4μg/mL mouse anti-PP2A-alpha/PPP2CA Antibody (orb654389) overnight at 4°C. DyLight®488 Conjugated Goat Anti-Mouse 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 U937 cells using anti-PP2A-alpha/PPP2CA antibody (orb654389). Overlay histogram showing U937 cells stained with orb654389 (Blue line). The cells were blocked with 10% normal goat serum. And then incubated with mouse anti-PP2A-alpha/PPP2CA Antibody (orb654389, 1μg/1x10^6 cells) for 30 min at 20°C. DyLight®488 conjugated goat anti-mouse IgG (5-10μg/1x10^6 cells) was used as secondary antibody for 30 minutes at 20°C. Isotype control antibody (Green line) was mouse IgG (1μg/1x10^6) used under the same conditions. Unlabelled sample (Red line) was also used as a control.

IHC analysis of PP2A-alpha/PPP2CA using anti-PP2A-alpha/PPP2CA antibody (orb654389). PP2A-alpha/PPP2CA 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.
