Anti-EIF5B Antibody Picoband®

Western blot analysis of EIF5B using anti-EIF5B antibody (A04604-1).
Electrophoresis was performed on a 8% 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 A549 whole cell lysates,
Lane 2: human HepG2 whole cell lysates,
Lane 3: human Jurkat whole cell lysates,
Lane 4: human K562 whole cell lysates,
Lane 5: rat RH35 whole cell lysates,
Lane 6: mouse NIH/3T3 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-EIF5B antigen affinity purified polyclonal antibody (A04604-1) 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 ECL Plus Western Blotting Substrate (Catalog # AR1196-200) with Tanon 5200 system. A specific band was detected for EIF5B at approximately 200 kDa. The expected band size for EIF5B is at 139 kDa.

IHC analysis of EIF5B using anti-EIF5B antibody (A04604-1).
EIF5B was detected in a paraffin-embedded section of human stomach 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-EIF5B Antibody (A04604-1) 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 EIF5B using anti-EIF5B antibody (A04604-1).
EIF5B was detected in an immunocytochemical section of A549 cells. 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-EIF5B Antibody (A04604-1) overnight at 4°C. Fluoro488 Conjugated Goat Anti-Rabbit IgG (BA1127) was used as secondary antibody at 1:500 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.

Immunoprecipitating EIF5B in HepG2 whole cell lysate.
Western blot analysis of EIF5B using anti-EIF5B antibody (A04604-1).
Lane 1: HepG2 whole cell lysates (30ug),
Lane 2: Rabbit control IgG instead of anti-EIF5B antibody in HepG2 whole cell lysate,
Lane 3: anti-EIF5B antibody (2μg) + HepG2 whole cell lysate (500μg).
After electrophoresis, proteins were transferred to a membrane. Then the membrane was incubated with rabbit anti-EIF5B antigen affinity purified polyclonal antibody (A04604-1) at a dilution of 0.5 μg/mL and probed with a goat anti-rabbit IgG-HRP secondary antibody (Catalog # BA1054). The signal is developed using ECL Plus Western Blotting Substrate (Catalog # AR1197). A specific band was detected for EIF5B at approximately 200 kDa. The expected band size for EIF5B is at 139 kDa.

Flow Cytometry analysis of Jurkat cells using anti-EIF5B antibody (A04604-1).
Overlay histogram showing Jurkat cells stained with A04604-1 (Blue line). To facilitate intracellular staining, cells were fixed with 4% paraformaldehyde and permeabilized with permeabilization buffer. The cells were blocked with 10% normal goat serum. And then incubated with rabbit anti-EIF5B Antibody (A04604-1, 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.
