Polybead® Carboxylate Microspheres 4.50μm

Polybead® Carboxylate Microspheres are monodisperse polystyrene microspheres that contain surface carboxyl groups. This allows for the covalent binding of proteins to the bead surface. These microspheres are packaged as 2.5% solids (w/v) aqueous suspensions.
