    All lanes : Anti-Interferon alpha 2 antibody [EPR19074] (ab196221) at 1/5000 dilution

    Lane 1 : HEK-293T (human epithelial cell line from embryonic kidney transformed with large T antigen) transfected with an empty vector, containing a GFP-Myc-tag, whole cell lysate
    Lane 2 : HEK-293T transfected with Interferon alpha 2 expression vector containing a GFP-Myc-tag, whole cell lysate

    Developed using the ECL technique.

    Predicted band size: 22 kDa
    Observed band size: 50 kDa
    why is the actual band size different from the predicted?


    Exposure time: 3 seconds


    Blocking and dilution buffer: 5% NFDM/TBST.

    The molecular mass observed is due to the presence of the GFP epitope tag on full length IFN alpha 2.

    Immunoprecipitation - Anti-Interferon alpha 2 antibody [EPR19074] (ab196221)

    Interferon alpha 2 was immunoprecipitated from 0.35 mg of HEK-293T (human epithelial cell line from embryonic kidney transformed with large T antigen) (transfected with Interferon alpha 2 expression vector containing a GFP-His-tag) whole cell lysate using ab196221 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab196221 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/10,000 dilution.

    Lane 1: HEK-293T (transfected with Interferon alpha 2 expression vector containing a GFP-His-tag) whole cell lysate 10 μg (Input).

    Lane 2: ab196221 IP in HEK-293T (transfected with Interferon alpha 2 expression vector containing a GFP-His-tag) whole cell lysate.

    Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab196221 inHEK-293T (transfected with Interferon alpha 2 expression vector containing a GFP-His-tag) whole cell lysate 

    Blocking and dilution buffer and concentration: 5% NFDM/TBST.
    Exposure time: 1 second.
