New developments in affinity chromatography

The design, synthesis and chromatographic operation of a new range of stable and selective immobilized dye affinity adsorbents for potential application in the purification of pharmaceutical proteins is described. Computer aided molecular design has been exploited to design novel dye ligands which show a predictable selectivity for the target protein and which, when coupled to stable perfluoropolymer supports, yield high capacity, low leakage adsorbents for affinity chromatography. It is anticipated that these new materials will withstand the rigorous conditions required for sanitization and cleaning in situ of industrial scale processes. Copyright © 1990 John Wiley & Sons Ltd.
