amphoteric , isoelectric agarose membranes , as devised by martin and hampson [ martin , a.j.p . and hampson , f. ( 1978 ) j. chromatogr . 159 , 101-110 ] , are found unsuitable for blocking electroendosmosis in multi-compartment electrolysers during preparative isoelectric focusing , due to the poor and highly unpredictable incorporation of carboxyls and amino groups on the polysaccharide moiety .
