Abstract: | Electron donor acceptor gels based on cyanocarbons have been tested for human serum protein adsorption in the absence of salt-promotion by water-structuring salt. This phenomenon was compared with a normal adsorption process in the presence of salt. The tricyanoaminopropene-divinyl sulfone-agarose displayed unusual protein adsorption properties as binding could occur both independently or dependently of the salt-promotion. The absence of hydrophobic or ionic character of the salt-independent interaction suggests an electron donor acceptor adsorption mechanism which is shown, for the first time, to occur independently of salt-promotion in aqueous solution. Study of the protein adsorption specificity showed similar protein selectivity for the fractions adsorbed in both conditions. |
