    Lane 1: Wild type HAP1 whole cell lysate (20 µg)
    Lane 2: p53 knockout HAP1 whole cell lysate (20 µg)
    Lane 3: HEK293 whole cell lysate (20 µg)
    Lane 4: A431 whole cell lysate (20 µg)

    Lanes 1 - 4: Merged signal (red and green). Green - ab32389 observed at 50 kDa. Red - loading control, ab9484, observed at 37 kDa.

    ab32389 was shown to specifically react with p53 in wild type HAP1 cells. No band was observed when p53 knockout samples were used. Wild-type and p53 knockout samples were subjected to SDS-PAGE. ab32389 and ab9484 (Mouse anti-GAPDH loading control) were incubated overnight at 4°C at 1/1000 dilution 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 1/20000 dilution for 1 hour at room temperature before imaging.

    ab32389 staining p53 in wild-type Hap1 cells (top panel) and p53 knockout Hap1 cells (bottom panel). The cells were fixed with 100% methanol (5 min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated with ab32389 at 1µg/ml concentration and ab7291 (Mouse monoclonal to alpha Tubulin) at 1/1000 dilution overnight at +4°C, followed by a further incubation at room temperature for 1h with a goat secondary antibody to rabbit IgG (Alexa Fluor® 488) (ab150081) at 2 μg/ml (shown in green) and a goat secondary antibody to mouse IgG (Alexa Fluor® 594) (ab150120) at 2 μg/ml (shown in pseudo color red).  Nuclear DNA was labelled in blue with DAPI.

    Image was taken with a high-content analysis system (Perkin Elmer, Operetta CLS™).
