Western blot - Human PTGS2 knockout HeLa cell line (ab255420)All lanes : Anti-COX2 / Cyclooxygenase 2 antibody [EPR12012] (ab179800) at 1/1000 dilution
Lane 1 : A549 cell lysate
Lane 2 : U-87 MG cell lysate
Lane 3 : Wild-type HeLa cell lysate
Lane 4 : PTGS2 knockout HeLa cell lysate
Lysates/proteins at 20 µg per lane.
Secondary
All lanes : Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) at 1/20000 dilution
Predicted band size: 69 kDa
Additional bands at: 37 kDa (possible Loading Control)Lanes 1 - 4: Merged signal (red and green). Green - ab179800 observed at 75 kDa. Red - loading control, ab8245 observed at 37 kDa.
ab179800 was shown to react with COX2 / Cyclooxygenase 2 in wild-type HeLa cells. Loss of signal was observed when knockout cell line ab255420 (knockout cell lysate ab263795) was used. Wild-type and COX2 / Cyclooxygenase 2 knockout samples were subjected to SDS-PAGE. ab179800 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 20000 dilution for 1 hour at room temperature before imaging.
