IHC analysis of EIF4A using anti-EIF4A antibody (orb570332). EIF4A was detected in paraffin-embedded section of human colon cancer tissues. Heat mediated antigen retrieval was performed in citrate buffer (pH6, epitope retrieval solution) for 20 mins. The tissue section was blocked with 10% goat serum. The tissue section was then incubated with 1μg/ml rabbit anti-EIF4A Antibody (orb570332) 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.

Western blot analysis of EIF4A (A1, 2, 3) using anti-EIF4A (A1, 2, 3) antibody (orb570332). 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 Jurkat whole cell lysates, Lane 3: human A431 whole cell lysates, Lane 4: human HEK293 whole cell lysates, Lane 5: human HepG2 whole cell lysates, Lane 6: human A549 whole cell lysates, Lane 7: human U87 whole cell lysates, Lane 8: human K562 whole cell lysates, Lane 9: rat PC-12 whole cell lysates, Lane 10: mouse spleen tissue lysates, Lane 11: mouse thymus tissue lysates, Lane 12: mouse lung tissue lysates, Lane 13: 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-EIF4A (A1, 2, 3) antigen affinity purified polyclonal antibody (Catalog # orb570332) 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 1:10000 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 EIF4A (A1, 2, 3) at approximately 46KD. The expected band size for EIF4A (A1, 2, 3) is at 46KD.
