This work addresses the obtaining and characterization of alginate-guar gum matrix,cross-linked with epichlorohydrin in the presence of different flexible chain polymers:polyvinyl alcohol, polyvinyl pyrrolidine and Pluronic® F68. These matrixes were usedfor the adsorption of chymotrypsinogen and showed an increasing uptake in presence ofthe flexible chain polymer in the sense: none < Pluronic 68 < polyvinyl pyrrolidine
