    Unpurified ab40759 staining Smad4 in rat femur tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with formaldehyde and blocked with 1% BSA for 20 minutes at 22°C; antigen retrieval was by heat mediation in a citrate buffer pH6.0. Samples were incubated with primary antibody (1/200 in blocking buffer) for 2 hours at 20°C. An undiluted HRP-conjugated goat anti-rabbit IgG polyclonal (1/250) was used as the secondary antibody.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab40759).

    Lane 1: Wild type HAP1 whole cell lysate (20 µg)
    Lane 2: SMAD4 knockout  HAP1 whole cell lysate (20 µg)
    Lane 3: HepG2 whole cell lysate (20 µg)
    Lane 4: Jurkat whole cell lysate (20 µg)

    Lanes 1 - 4: Merged signal (red and green). Green - ab40759 observed at 60 kDa. Red - loading control, ab9484, observed at 37 kDa.

    ab40759 was shown to specifically react with SMAD4 in wild type HAP1 cells. No band was observed when SMAD4 knockout HAP1 samples were used. Wild-type and SMAD4 knockout samples were subjected to SDS-PAGE. Ab40759 and ab9484 (Mouse anti GAPDH loading control) were incubated overnight at 4°C at 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.
