The sample well of each lane was loaded with 50 ug of sample under reducing conditions. Lane 1: human HepG2 whole cell lysates Lane 2: human K562 whole cell lysates Lane 3: human THP-1 whole cell lysates Lane 4: human HEK293 whole cell lysates Lane 5: human A549 whole cell lysates Lane 6: human Caco-2 whole cell lysates Lane 7: rat RH35 whole cell lysates Lane 8: 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 mouse anti-COMT antigen affinity purified monoclonal antibody 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-mouse 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 with Tanon 5200 system. A specific band was detected for COMT at approximately 29KD. The expected band size for COMT is at 29KD.
