Affinity Selection of Peptide Binders with Magnetic Beads

We describe a new method for affinity selection of peptide binders for soluble protein targets using magnetic beads via organic phase separation (MOPS) from a phage display library. As a model target molecule, a mouse monoclonal antibody against human integrin α9β1 (Y9A2) immobilized onto protein G magnetic beads was incubated with a 15-mer or 20-mer random peptide phage-display library.

MACS® Cell Separation - Miltenyi Biotec

The antibody fragments have a low affinity for cell surface epitopes. However, when the fragments are multimerized as a complex, they bind epitopes with high avidity and enable effective magnetic cell separation. REAlease Technology controls the multimer/ monomer state of the fragments and thus triggers the release of

This cell separation technique utilizes the potential to label cell surface markers with magnetic bead–tagged antibodies and the ability of a magnetic field to migrate the labeled particles from a distance. 1 This controlled migration by a magnetic force (magnetophoresis) is invaluable in separating heterogeneous cell populations and is the basis for magnetic-activated cell sorting (MACS).
