Affinity-independent elution of antibody-displaying phages using cleavable DNA linker containing streptavidin beads

The search for high-affinity antibodies from phage libraries by panning is often complicated by inefficient detachment of the captured phage particles from the antigen-coated solid phase. General elution methods, independent on the bioaffinity interaction, would be desirable for high-throughput antibody screening. We have developed a bioaffinity-independent elution method based on the use of commercially available streptavidin paramagnetic particles.
