title: Butyl-Toyopearl 650 as a new hydrophobic adsorbent for water-soluble enzyme proteins.
abstract: Butyl-Toyopearl 650, a butyl derivative of Toyopearl HW-65, was synthesized for use in hydrophobic chromatography. Water-soluble enzyme proteins were adsorbed on butyl-Toyopearl 650 in the presence of ammonium sulfate and eluted easily in the absence of the salt. Cytochrome c, myoglobin, and chymotrypsinogen A were successfully separated on a butyl-Toyopearl 650 column in order of their individual hydrophobicity by decreasing the concentration of ammonium sulfate contained in the buffer eluant. Based on these results, the use of butyl-Toyopearl 650 is demonstrated for the hydrophobic separation of water-soluble enzyme proteins.
