Performed under reducing conditions.

Predicted band size: 60 kDa

 ab209211 Anti-Catalase antibody [EPR20198] was shown to specifically react with Catalase in wild-type HeLa cells. Loss of signal was observed when knockout cell line ab265250 (knockout cell lysate ab256859) was used. Wild-type and Catalase knockout samples were subjected to SDS-PAGE. ab209211 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4°C at 1 in 2000 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.

Lanes 1 - 4: Merged signal (red and green). Green - ab209211 observed at 60 kDa. Red - loading control, ab8245, observed at 37 kDa.

ab209211 was shown to specifically react with CAT in wild-type HAP1 cells. No band was observed when CAT knockout samples were examined. Wild-type and CAT knockout samples were subjected to SDS-PAGE. Ab209211 and ab8245 (Mouse anti GAPDH loading control) were incubated overnight at 4°C at 1/2000 dilution and 1/10,000 dilution respectively.
