    This WB data was generated using the same anti-IRF2 antibody clone, EPR4644(2), in a different buffer formulation (cat# ab12474).

    Lane 1: Wild type HAP1 whole cell lysate (20 µg)
    Lane 2: IRF2 knockout HAP1 whole cell lysate (20 µg)
    Lane 3: HeLa whole cell lysate (20 µg)
    Lane 4: CACO2 whole cell lysate (20 µg)

    Lanes 1 - 4: Merged signal (red and green). Green - ab124744 observed at 48 kDa. Red - loading control, ab18058, observed at 130 kDa.

    ab124744 was shown to recognize IRF2 when IRF2 knockout samples were used, along with additional cross-reactive bands. Wild-type and IRF2 knockout samples were subjected to SDS-PAGE.  Ab124744 and ab18058 (Mouse anti Vinculin loading control) were incubated overnight at 4°C at 1/1000 and 1/10000 dilutions respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) ab216773 and 680CW Goat anti Mouse secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.

    Immunofluorescent analysis of 4% paraformaldehyde-fixed, 0.1% Triton X-100 permeabilized HeLa (Human epithelial cells from cervix adenocarcinoma) cells labeling IRF2 with ab124744 at 1/500 dilution, followed by Goat anti-rabbit IgG (Alexa Fluor® 488) (ab150077) secondary antibody at 1/500 dilution (green). Confocal image showing nuclear staining on HeLa cells.

    The nuclear counter stain is DAPI (blue). Tubulin is detected with ab7291 (anti-Tubulin mouse mAb) at 1/1000 dilution and ab150120 (AlexaFluor®594 Goat anti-Mouse secondary) at 1/500 dilution (red).
    The negative controls are as follows:
    -ve control 1: ab124744 at 1/500 dilution followed by ab150120 (AlexaFluor®594 Goat anti-Mouse secondary) at 1/500 dilution.
    -ve control 2: ab7291 (anti-Tubulin mouse mAb) at 1/1000 dilution followed by ab150077 (Alexa Fluor®488 Goat Anti-Rabbit IgG H&L) at 1/500 dilution.
