      All lanes : Anti-IL-18 antibody [EPR19954] (ab207324) at 1/200 dilution

      Lane 1 : Wild-type HEK293 whole cell lysate
      Lane 2 : IL-18 knockout HEK293 whole cell lysate

      Lysates/proteins at 20 µg per lane.

      Predicted band size: 22 kDa



      Lanes 1 - 2: Merged signal (red and green). Green - ab207324 observed at 22 kDa. Red - loading control, ab9484, observed at 37 kDa.

      ab207324 was shown to recognize IL-18 in wild-type HEK293 cells as signal was lost at the expected MW in IL-18 knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and IL-18 knockout samples were subjected to SDS-PAGE. Ab207324 and ab9484 (Mouse anti-GAPDH loading control) were incubated overnight at 4°C at 1/200 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.

      This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab207324).
