Study of lipoprotein sorption by some sulfoderivatives of chitosan

The possibility of deposition of lipoproteins from blood plasma by different chitosan sulfoderivatives has been demonstrated. The influence of structure, substitution degree and molecular weight of chitosan sulfates on lipoprotein sorption was studied as well as the influence of composition of chitosan interpolymer complexes with dextransulfate. Affinic sorbents based on the silica matrixes and sulfoderivatives of chitosan as a ligand can reveal high specificity in relation to low density lipoprotein, but do not cause essential changes in blood count during contact with blood.
