Protein and DNA adsorption on dehydroxylated and aluminated silochromes

A macroporous silica - silochrom - used for immobilization and purification of biopolymers was modified by dehydroxylation and alumination. The adsorption capacity of the modified silochroms for proteins and DNA is higher than that of the initial sorbent. The biopolymers adsorbed on aluminated silochrom are strongly attached to its surface.
