  • All lanes : Anti-p66 beta antibody (ab76925) at 0.04 µg/ml

    Lane 1 : HeLa whole cell lysate at 50 µg
    Lane 2 : HeLa whole cell lysate at 15 µg
    Lane 3 : HeLa whole cell lysate at 5 µg
    Lane 4 : 293T whole cell lysate at 50 µg

    Predicted band size : 66 kDa
    Observed band size : 72 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 130 kDa. We are unsure as to the identity of these extra bands.
