Western blot analysis of WHSC1/NSD2 using anti-WHSC1/NSD2 antibody (A32441-1). 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 Hela whole cell lysates, Lane 2: monkey COS-7 whole cell lysates, Lane 3: human Raji whole cell lysates, Lane 4: human HEK293 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-WHSC1/NSD2 antigen affinity purified polyclonal antibody (Catalog # A32441-1) 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 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 WHSC1/NSD2 at approximately 70 kDa, 160 kDa. The expected band size for WHSC1/NSD2 is at 152 kDa.
