A method for the preparation of low molecular weight glutenin subunits (LMW-GS) of bread wheat without contamination by high molecular weight glutenin subunits (HMW-GS) or gliadins is described. Using a simple protocol based on the selective precipitation by acetone, two fractions are obtained that correspond to HMW-GS and LMW-GS. The protein fractions can be obtained either reduced or reduced and alkylated. The protocol can be scaled up to obtain large quantities of LMW-GS.
