Western blot - Human CHEK2 knockout HeLa cell line (ab264815)All lanes : Anti-Chk2 antibody [EPR19482] (ab207446) at 1/1000 dilution
Lane 1 : HeLa WT
Lane 2 : CHEK2 HeLa KO
Lane 3 : HEK-293
Lane 4 : MDA-MB-231
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: 61 kDa
Observed band size: 68 kDa why is the actual band size different from the predicted?Lanes 1-4: Merged signal (red and green). Green - ab207446 observed at 68 kDa. Red - loading control ab8245 observed at 37 kDa.
ab207446 Anti-Chk2 antibody [EPR19482] was shown to specifically react with Chk2 in wild-type HeLa cells. Loss of signal was observed when knockout cell line ab264815 (knockout cell lysate ab257104) was used. Wild-type and Chk2 knockout samples were subjected to SDS-PAGE. ab207446 and Anti-alpha Tubulin antibody [EP1332Y] - Microtubule Marker (ab52866) 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.
