Does anyone have any suggestions?  I understand that this is very general question.  Please let me know if you have any thoughts on this.

Alcohol dehydrogenase from yeast is a very sturdy and abundant protein.
Purification is easy (aceton precipitation, heat denaturing, ion
exchange chromatography, ammonium sulfate crystallisation). 

Activity is checked in a coupled spectrophotometric assay, which is an
important concept in itself.

ADH is a tetramere, so you can exemplify the differeences between native
and denaturing electrophoresis to.
