Figure 1. Western blot analysis of RALB using anti-RALB antibody (PB9795). Electrophoresis was performed on a 5-20% SDS-PAGE gel at 70V (Stacking gel) / 90V (Resolving gel) for 2-3 hours. Lane 1: Rat Brain Tissue Lysate at 50ug, Lane 2: Rat Thymus Tissue Lysate at 50ug, Lane 3: Rat Lung Tissue Lysate at 50ug, Lane 4: Mouse Spleen Tissue Lysate at 50ug, Lane 5: Mouse Liver Tissue Lysate at 50ug, Lane 6: HELA Whole Cell Lysate at 40ug, Lane 7: 22RV1 Whole Cell Lysate at 40ug. 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-RALB antigen affinity purified polyclonal antibody (Catalog # PB9795) at 0.5 microg/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 # EK1002) with Tanon 5200 system. A specific band was detected for RALB at approximately 23 kDa. The expected band size for RALB is at 23 kDa.
