A new protein adsorbent is introduced based on the coupling of the common buffer ion, tris(hydroxymethyl)aminomethane, to the agarose gel Sepharose HPfrom GEHealthcare Bio-Sciences AB, Uppsala, Sweden. The article describes the synthesis of the new adsorbent and the use of BSA as a model in a binding study. By optimization of the coupling procedure, a maximum ligand density of 63.5 μmol/mL gel could be obtained. Adsorption equilibria were investigated in the pH range 5.0-8.0 and at salt concentrations of 0-0.4 mol/L. Binding of BSA under different conditions indicated that both electrostatic interaction and hydrogen bonding were involved in the adsorption process where the former played a major role.
