Performed under reducing conditions.

Predicted band size: 21 kDa

This data was developed using the same antibody clone in a different buffer formulation (ab187643).

Lanes 1-4: Merged signal (red and green). Green - ab187643 observed at 20 kDa. Red - loading control ab8245 observed at 37 kDa.

 ab187643 Anti-CDC42 antibody [EPR15620] was shown to specifically react with CDC42 in wild-type HEK-293T cells. Loss of signal was observed when knockout cell line ab266522 (knockout cell lysate ab256868) was used. Wild-type and CDC42 knockout samples were subjected to SDS-PAGE. ab187643 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4°C at 1 in 5000 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 20000 dilution for 1 hour at room temperature before imaging.
