All lanes : Anti-EpCAM antibody [EPR20532-222] (ab213500) at 1/1000 dilution
Lane 1 : Wild-type A431 whole cell lysate
Lane 2 : EPCAM knockout A431 whole cell lysate
Lane 3 : HeLa whole cell lysate
Lysates/proteins at 20 µg per lane.
Performed under reducing conditions.
Predicted band size: 35 kDa
Observed band size: 35 kDaLanes 1 - 3: Merged signal (red and green). Green - ab213500 observed at 40 kDa. Red - loading control, ab7291 (Mouse anti-Alpha Tubulin [DM1A] observed at 55kDa.
ab213500 was shown to react with EpCAM in A431 wild-type cells in Western blot. Loss of signal was observed when EpCAM knockout sample was used. A431 wild-type and EpCAM knockout cell lysates were subjected to SDS-PAGE. Membranes were blocked in 3% Milk in TBS-T (0.1% Tween®) before incubation with ab213500 and ab7291 (Mouse anti-Alpha Tubulin [DM1A] overnight at 4°C at a 1 in 1000 dilution and a 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.
