Abstract:
A process for isolating a proteinaceous material in an aqueous sample comprising the steps:(a) providing an aqueous sample comprising a proteinaceous material, (b) contacting the aqueous sample with a solid phase having a surface on which is a mixture of hydrophobic groups and hydrophilic groups for binding the proteinaceous material to the solid phase, wherein the solid phase comprises magnetic solid particles having a diameter from &gE;1 nm to &lE;10 mm, and wherein the proteinaceous material is bound reversibly and nonspecifically to said hydrophobic groups, (c) removing unbound components from the solid phase, (d) releasing the bound proteinaceous material from the solid phase, and (e) removing the magnetic solid particles by magnetic separation, thereby isolating the proteinaceous material.
