Affinity Chormatography Removes Endotoxins - Porous cellulose beads impregnated with poly(µ-lysine) are a selective packing to purify protein solutions. - BioPharm International. Protein solutions used for research, vaccines, or therapeutics need to be free of contaminants.
One of the chief concerns is the presence of endotoxins (lipopolysaccharides) because their removal from protein solutions is a challenge. Typically, removal techniques utilize adsorption onto surfaces of beads in batch reactions, onto beads packed in columns, or onto membrane surfaces. When poly(ε-lysine), currently used as a food preservative, is impregnated into cellulose beads, it can be safely used as a ligand for endotoxin removal using affinity chromatography.
