    Lanes 1 - 4: Merged signal (red and green). Green - ab224642 observed at 44-46 kDa. Red - loading control, ab130007, observed at 130 kDa.

    ab224642 was shown to recognize RUNX3 in wild-type HAP1 cells as signal was lost at the expected MW in RUNX3 knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and RUNX3 knockout samples were subjected to SDS-PAGE. Ab224642 and ab130007 (Mouse anti-Vinculin loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/20000 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 1/20000 dilution for 1 hour at room temperature before imaging.
