  • All lanes : Anti-Tryptophan Hydroxylase (phospho S260) antibody (ab30574) at 1/1000 dilution

    Lane 1 : rat brain stem lysate (control)
    Lane 2 : rat brain stem lysate, incubated with S260 phosphopeptide (negative control)
    Lane 3 : rat brain stem lysate, incubated with corresponding non phosphopeptide.

    Lysates/proteins at 15 µg per lane.

    Predicted band size : 51 kDa
    Observed band size : 55 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 48 kDa,59 kDa,<43 kDa. We are unsure as to the identity of these extra bands.
