Anti-EWSR1 Antibody Picoband®

Western blot analysis of EWSR1 using anti-EWSR1 antibody (PB9585).
Electrophoresis was performed on a 10% SDS-PAGE gel at 80V (Stacking gel) / 120V (Resolving gel) for 2 hours. The sample well of each lane was loaded with 30 ug of sample under reducing conditions.
Lane 1: human Jurkat whole cell lysates,
Lane 2: human K562 whole cell lysates,
Lane 3: human Hela whole cell lysates,
Lane 4: human RT4 whole cell lysates,
Lane 5: rat testis tissue lysates,
Lane 6: rat C6 whole cell lysates,
Lane 7: mouse testis tissue 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-EWSR1 antigen affinity purified polyclonal antibody (PB9585) 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 (Catalog # BA1054) at a dilution of 1:5000 for 1.5 hour at RT. The signal is developed using an ECL Plus Western Blotting Substrate (Catalog # AR1196-200) with Tanon 5200 system. A specific band was detected for EWSR1 at approximately 90-95 kDa. The expected band size for EWSR1 is at 69 kDa.

IHC analysis of EWSR1 using anti-EWSR1 antibody (PB9585).
EWSR1 was detected in a paraffin-embedded section of human testis cancer 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-EWSR1 Antibody (PB9585) overnight at 4°C. Peroxidase Conjugated Goat Anti-rabbit IgG was used as secondary antibody and incubated for 30 minutes at 37°C. The tissue section was developed using HRP Conjugated Rabbit IgG Super Vision Assay Kit (Catalog # SV0002) with DAB as the chromogen.

IF analysis of EWSR1 using anti-EWSR1 antibody (PB9585) and anti-Tubulin Alpha antibody (M03989-3).
EWSR1 was detected in immunocytochemical section of Hela cell. 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-EWSR1 Antibody (PB9585) and mouse anti-Tubulin Alpha antibody (M03989-3) overnight at 4°C. Fluoro488 Conjugated Goat Anti-Rabbit IgG (BA11245) and Cy3 Conjugated Goat Anti-Mouse IgG (BA1031) were used as secondary antibody at 1:500 dilution and incubated for 30 minutes at 37°C. Visualize using a fluorescence microscope and filter sets appropriate for the label used.

After electrophoresis, proteins were transferred to a membrane. Then the membrane was incubated with rabbit anti-EWSR1 antigen affinity purified polyclonal antibody (PB9585) at a dilution of 0.5 μg/mL and probed with a goat anti-rabbit IgG-HRP secondary antibody (Catalog # BA1054).

Flow Cytometry analysis of RT4 cells using anti-EWSR1 antibody (PB9585).
Overlay histogram showing RT4 cells stained with PB9585 (Blue line). The cells were fixed with 4% paraformaldehyde and blocked with 10% normal goat serum. And then incubated with rabbit anti-EWSR1 Antibody (PB9585, 1 μg/1x10⁶ cells) for 30 min at 20°C. Fluoro488 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.
