Cation exchangers for selective sorption of large proteins.
The sorption of bovine serum albumin, cytochrom c and fibrinogen on the series of carboxylic cation-exchangers with various concentrations of ionogenic groups has been investigated. The dependence of sorption selectivity on protein size and on concentration of ionogenic groups was demonstrated.
