Summary

To study the adsorption behaviour of serum proteins on different chemical moieties as present on the surface of polymers, a chromatographic method was developed: the relative adsorptivity of the proteins on substituted Sepharose 4B gels [1] was determined by measurng their elution volumes under standnardised conditions. The reseults show that the interaction between the proteins and gels is dependent on both and difers markedly in strength.
