MW: 55kD. Molecular Biology GradeSingle band (SDS-PAGE). Streptavidin is a biotin-binding protein which binds 4 moles of biotin per mole of protein under high affinity(Kd~10e-15). Due to the lack of carbonate side chains present on avidin and a neutral isoelectric point, streptavidin maintains less non-specific binding tan avidin.
