Thermo Scientific Immobilized NeutrAvidin Products are superior alternatives to avidin and streptavidin agarose and acrylamide beaded affinity resins.

NeutrAvidin Protein is a modified avidin derivative that combines several key features to provide a biotin-binding protein with exceptionally low nonspecific binding properties. Native avidin is heavily glycosylated, resulting in its high pI and nonspecific binding properties. By contrast NeutrAvidin Protein contains no carbohydrate and has a near-neutral isoelectric point (6.3), features that provide for very low nonspecific binding and broader utility in a variety of applications.
