Abstract: A method for treating capillary walls exposable to protein solutes is provided that promotes reversible interactions between the protein solutes and the wall. Thus a small bore capillary tube, useful for reproducible protein electrophoretic separations, includes an interfacial phase comprising agarose that is bonded to the bore. Pretreatment of the capillary walls with silylation reagents forms an intermediate layer that provides a determinable cathodic electroosmotic flow magnitude that remains constant even if the buffer pH fluctuates between 4-7. The modified capillaries can be used repeatedly and they exhibit selectivity in protein separations.
