NeutrAvidin beads, like Streptavidin beads, can immobilize biotin-labeled compounds and antibodies, DNA, etc. and can be used in a wide range of applications.
NeutrAvidin beads may have slight non-specific adsorption from sugar chains. However, since it does not have a RYD sequence, it suppresses non-specific adsorption derived from cell adhesion proteins compared to Streptavidin beads.
