  • All lanes : Anti-ERp57 antibody (ab88098) at 1 µg/ml

    Lane 1 : Wild-type HAP1 whole cell lysate
    Lane 2 : PDIA3 (ERp57) knockout HAP1 whole cell lysate

    Lysates/proteins at 20 µg per lane.

    Predicted band size: 57 kDa



    Lanes 1 - 2: Merged signal (red and green). Green - ab88098 observed at 57 kDa. Red - loading control, ab9484, observed at 37 kDa.

    ab88098 was shown to recognize PDIA3 in wild-type HAP1 cells as signal was lost at the expected MW in PDIA3 (ERp57) knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and PDIA3 (ERp57) knockout samples were subjected to SDS-PAGE. Ab88098 and ab9484 (Mouse anti-GAPDH loading control) were incubated overnight at 4°C at 1 μg/ml and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.
