Western blot analysis of ID2 using anti-ID2 antibody (A00417-3).
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 30ug of sample under reducing conditions.
Lane 1: human HEK293 whole cell lysates,
Lane 2: human HepG2 whole cell lysates,
Lane 3: human Caco-2 whole cell lysates,
Lane 4: human U87 whole cell lysates,
Lane 5: human PC-3 whole cell lysates,
Lane 6: human HL-60 whole cell lysates,
Lane 7: human Hela whole cell lysates,
Lane 8: rat liver tissue lysates,
Lane 9: rat ovary tissue lysates,
Lane 10: mouse liver tissue lysates,
Lane 11: mouse lung tissue lysates,
Lane 12: mouse spleen tissue 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-ID2 antigen affinity purified polyclonal antibody (Catalog # A00417-3) at 0.25 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 Enhanced Chemiluminescent detection (ECL) kit (Catalog # EK1002) with Tanon 5200 system. A specific band was detected for ID2 at approximately 18KD. The expected band size for ID2 is at 18KD.
