– TargetMol Magrose Beads Protein A (10-30 μm) are antibody purification beads that utilize bio-nanosurface technology to covalently encapsulate Protein A onto the surface of NHS-activated superparamagnetic microspheres in a high-density, targeted manner to form composite particles. TargetMol Magrose Beads Protein A (10-30 μm) have a large specific surface area, which dramatically reduces the time required for antibody adsorption. Antibody adsorption can be completed in less than 10 minutes and antibody purification in less than 30 minutes. The product is reusable. Users can choose the type of beads according to the source and subtype of the target antibody.
