    Predicted band size: 24 kDa
    Observed band size: 24 kDa



    This data was developed using the same antibody clone in a different buffer formulation (ab188574).

    Lanes 1-4: Merged signal (red and green). Green - ab188574 observed at 24 kDa. Red - loading control, ab8245 observed at 37 kDa.

    ab188574 Anti-RAB8A antibody [EPR14873] was shown to specifically react with RAB8A in wild-type HeLa cells. Loss of signal was observed when knockout cell line ab264993 (knockout cell lysate ab257195) was used. Wild-type and RAB8A knockout samples were subjected to SDS-PAGE. ab188574 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4°C at 1 in 1000 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1 in 10000 dilution for 1 hour at room temperature before imaging.
