Aquaporin-3 Antibody - BSA Free

A: Yes, the theoretical size of AQP3 is 31 kDa, which would be expected under reduced conditions with a sample. We have not characterized any of the other bands in the overexpressed lysate lane. Because this is a native lysate, any modifications that may take place could cause smearing and extra bands in the lysate sample. AQP3 is extensively modified because it is a glycoprotein, glycosylation often shows up as multiple bands with smearing when run under native conditions.  This overexpression lysate is meant to only act as a positive control in WB experiments requiring a native control. Furthermore, the lane on the right side of the blot is showing detection of the lysate using an anti-Flag tag antibody, since the construct used for overexpression contains a Flag tag.
