What is the efficiency when immobiliding antibodies?

If binding is performed when 50 μg of antibodies is supplied to 1 mg of NHS beads, approximately 20 – 40 μg will be bound, although the result varies depending on the antibody animal, subclass, and clone. It is possible to increase the amount that is bound by increasing the amount on feed. When streptavidin beads are used, up to approximately 10 μg of biotin-modified antibodies will bond to 1 mg of Streptavidin beads or NeutrAvidin beads, although this also varies depending on the antibody.
