Study on the purification of extensin from the cell wall of carrot root
The extensins from the cell wall of carrot root were purified by CM-cellulose and Sephadex G-75 chromatography. Two components were received from the cell wall proteins of carrot root. The amount of amino acid and molecular mass of these components were determined through amino acid analysis instrument and SDS-PAGE, respectively. The compound belonging to extensin was identified according to the amount of amino acid and molecular mass of these components.
