Western blot analysis of SOX2 using anti-SOX2 antibody (A00105-1).
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 30 ug of sample under reducing conditions.
Lane 1: human U251 whole cell lysates,
Lane 2: human 293T whole cell lysates,
Lane 3: rat PC-12 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-SOX2 antigen affinity purified poly clonal antibody (Catalog # A00105-1) 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 ING-HRP secondary antibody at a dilution of 1:5000 for 1.5 hour at RT. The signal is developed using an Enhanced Luminescence detection (ECL) kit (Catalog # EK1002) with Anon 5200 system. A specific band was detected for SOX2 at approximately 36 kDa. The expected band size for SOX2 is at 34 kDa.
