Figure 1. Western blot analysis of PCK2 using anti-PCK2 antibody (A04772-1). 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 50ug of sample under reducing conditions. Lane 1: human HepG2 whole cell lysates, Lane 2: human Raji whole cell lysates, Lane 3: human T-47D whole cell lysates, Lane 4: human U2OS whole cell lysates, Lane 5: human A431 whole cell lysates, Lane 6: human K562 whole cell lysates, Lane 7: human PC-3 whole cell lysates, Lane 8: rat brain tissue lysates, Lane 9: rat spleen tissue lysates, Lane 10: rat kidney tissue lysates, Lane 11: rat liver tissue lysates, Lane 12: mouse brain tissue lysates, Lane 13: mouse kidney tissue lysates, Lane 14: mouse Neuro-2a 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-PCK2 antigen affinity purified polyclonal antibody (Catalog # A04772-1) at 0.25 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 PCK2 at approximately 71KD. The expected band size for PCK2 is at 71KD.
