On denatured gels, I can easily see the monomer. On native gels, it is not possible to get the monomer (even not with high Urea concentrations, 1M). Is this protein normally in a tetramer?

Prealbumin is a tetramer under native conditions. It has a molecular weight of ~ 56,000 Da which consists of 4 subunits of ~ 14,000 Da each. When the lab runs native electrophoresis on this protein, we also only see the tetramer, and the monomer is only seen under reduced and denatured conditions.
