REP.G1888

Protein j in saline extracts of barley and malt can be detected by the immunochemical methods of double diffusion and immunoeletrophoretic analysis. technique of identifying alpha. and beta.amyyla:sc among tht: proteins U us detect,ed has been perfected. Some results of the study of these, amylases b ' immunochemical methods are described. although immunochemically identical,the beta.amylases of barlcy and malt are slown to prcsent differences in at least two physiochemical propertics. The, beta.amybse of barley is less soluble in water and migrates more rapidly at pH82 than beta-amylase of malt. It appear that alppha-amylase docs Hot in barley, evcn in trace amounts or in an inactive form calculations of alpha- and beta-amylase mobilities and an evaluation of the diffusion efficient of alpha-amylase are reported.
