Automated Ligand Fishing Using Human Serum Albumin-Coated Magnetic Beads

Abstract

Human serum albumin, HSA, was immobilized onto the surface of silica-based magnetic beads. The beads were used to isolate known HSA ligands from a mixture containing ligands and nonligands. The separation was accomplished manually and was also automated. The results indicate that an automated "ligand-fishing" technique can be developed using magnetic beads containing an immobilized protein.
