Affinity Magnetic Separation

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.

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).

Nov 06, 2020 The detailed analysis has shown that MNP3 has sufficient magnetic force as a nanomaterial for magnetic separation. The His-tagged protein is trapped by the formation of a complex with Ni on MNPs. When imidazole, which has a higher affinity for metals than histidine, is added, the metal forms a complex with imidazole, which causes the protein ...

Nov 26, 2004 Magnetic affinity particles are currently used mainly in molecular biology (especially for nucleic acids separation), cell biology and microbiology (separation of target cells) and as parts of the procedures for the determination of selected analytes using magnetic ELISA and related techniques (especially determination of clinical markers and ...
