    Lane 1 : Wild-type HEK-293T cell lysate
    Lane 2 : DROSHA knockout HEK-293T cell lysate
    Lane 3 : HeLa cell lysate

    Lysates/proteins at 20 µg per lane.

    Performed under reducing conditions.

    Predicted band size: 159 kDa
    Observed band size: 159 kDa



    This data was developed using the same antibody clone in a different buffer formulation (ab183732).

    Lanes 1-3: Merged signal (red and green). Green - ab183732 observed at 159 kDa. Red - loading control, ab8245 observed at 37 kDa.

    ab183732 Anti-Drosha antibody [EPR12794] was shown to specifically react with Drosha in wild-type HEK293T cells. Loss of signal was observed when knockout cell line ab266217 (knockout cell lysate ab257171) was used. Wild-type and Drosha knockout samples were subjected to SDS-PAGE. ab183732 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4°C at 1 in 1000 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1 in 10000 dilution for 1 hour at room temperature before imaging.

    Flow Cytometry analysis of Jurkat (human acute T cell leukemia) cells labeling Drosha with purified ab183732 at 1/230 dilution (10ug/ml) (red). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. A Goat anti rabbit IgG (Alexa Fluor® 488)(1/2000 dilution) was used as the secondary antibody. Rabbit monoclonal IgG (Black) was used as the isotype control, cells without incubation with primary antibody and secondary antibody (Blue) was used as the unlabeled control.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab183732).
