      Developed using the ECL technique.

      Performed under reducing conditions.

      Predicted band size: 26 kDa
      Observed band size: 37 kDa
      why is the actual band size different from the predicted?
      Additional bands at: 50 kDa, 63 kDa. We are unsure as to the identity of these extra bands.


      Exposure time: 150 seconds


      Surfactant Protein A/PSAP contains a number of potential glycosylation sites and other post translational modifications (SwissProt) which may explain its migration at a higher molecular weight than predicted.
