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.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of Human colon tissue labeling IRF2 with purified ab124744 at 1/50. Heat mediated antigen retrieval was performed using Tris/EDTA buffer pH 9. Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/500 dilution was used as the secondary antibody. Nucleus staining on epithelium of human colon was observed. Negative control using PBS instead of primary antibody. Counterstained with Hematoxylin.
