Plain polystyrene beads microspheres are ideal for protein adsorption, and have been utilized in a range of diagnostic tests and assays. Surface modified microspheres are available with carboxyl or primary amine groups for covalent ligand attachment. Affinity binding systems offer simple and efficient ligand attachment. Coatings of Fc binding proteins are able to orient antibodies for optimal activity, and streptavidin offers extremely stable attachment of biotinylated molecules, such as proteins, peptides, and oligonucleotides.
