Western blot analysis of IL2 Receptor beta/p75/IL2RB using anti-IL2 Receptor beta/p75/IL2RB antibody (orb692187). 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 30ug of sample under reducing conditions. Lane 1: human HeLa whole cell lysates, Lane 2: human Hek293 whole cell lysates, Lane 3: human K562 whole cell lysates, Lane 4: human THP-1 whole cell lysates, Lane 5: rat PC-12 whole cell lysates, Lane 6: mouse intestine tissue lysates, Lane 7: mouse RAW264.7 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-IL2 Receptor beta/p75/IL2RB antigen affinity purified polyclonal antibody (Catalog # orb692187) 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 IL2 Receptor beta/p75/IL2RB at approximately 75KD. The expected band size for IL2 Receptor beta/p75/IL2RB is at 75KD.

IF analysis of IL2 Receptor beta/p75/IL2RB using anti- IL2 Receptor beta/p75/IL2RB antibody (orb692187). IL2 Receptor beta/p75/IL2RB was detected in immunocytochemical section of A549 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 5μg/mL rabbit anti- IL2 Receptor beta/p75/IL2RB Antibody (orb692187) 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 U20S cells using anti-IL2 Receptor beta/p75/IL2RB antibody (orb692187). Overlay histogram showing U20S cells stained with orb692187 (Blue line). The cells were blocked with 10% normal goat serum. And then incubated with rabbit anti-IL2 Receptor beta/p75/IL2RB Antibody (orb692187, 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.

IHC analysis of IL2 Receptor beta/p75/IL2RB using anti-IL2 Receptor beta/p75/IL2RB antibody (orb692187). IL2 Receptor beta/p75/IL2RB was detected in a paraffin-embedded section of human appendicitis 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-IL2 Receptor beta/p75/IL2RB Antibody (orb692187) 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.
