Purification of Betaine-Aldehyde Dehydrogenase from Spinach Leaves and Preparation of Its Antibody1

Abstract
Betaine-aldehyde dehydrogenase was purified from spinach leaves and characterized. The Molecular weight of the enzyme was estimated to be 120 kDa by a gel filtration chromatorgraphy. The enzyme was judged to consist of two identical pieces of the monomeric subunit with molecular weight of 60 kDa. A specific polyclonal antibody was raised against the enzyme subunit.
