Figure 1. Western blot analysis of DLL1 using anti-DLL1 antibody (A02513-1). 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 HELA whole cell lysates, Lane 2: monkey COS-7 whole cell lysates, Lane 3: huamn Jurkat whole cell lysates, Lane 4: huamn Raji whole cell lysates, Lane 5: human SW620 whole cell lysates, Lane 6: human HepG2 whole cell lysates, Lane 7: human U20S whole cell lysates, Lane 8: rat heart tissue lysates, Lane 9: rat C6 whole cell lysates, Lane 10: mouse heart tissue lysates, Lane 11: mouse Neuro-2a whole cell lysates, Lane 12: mouse RAW264.7 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-DLL1 antigen affinity purified polyclonal antibody (Catalog # A02513-1) 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 1:10000 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 DLL1 at approximately 78KD. The expected band size for DLL1 is at 78KD.
