Streptavidin (SA) has an extraordinarily high affinity for biotin with a dissociation constant (Kd) on the order of 10−14 mol/L, the Biotinylated protein can bind to the SA beads irreversibly. The Magenetic beads are pre-coupled with Streptavidin tetramer protein and blocked with BSA, it is a ready-to-use beads, which can be used for binding biotinylated proteins and antibodies.
