Study on Extensin Purification from the Cell Wall of Soybean Dreg

Abstract

Abstract: The extensins extracted from the cell wall of soybean dregs were purified by CM-cellulose and Sephadex G-75chromatography. Three components were attained from the cell wall proteins of soybean dregs by CM-cellulose chromatography.The amount of amino acid and molecular mass of these components were determined through Amino Acid Analysis Instrumentand SDS-PAGE, respectively. The compound belonging to extensin was identified according to the amount of amino acid andmolecular mass of these components obtained.

Key words: soybean dregs, extensin, purification
