Polybead ® Amino Microspheres A2dm
Polybead ® Amino Microspheres are monodisperse polystyrene microspheres that contain surface
primary amine groups. Protein coupling using glutaraldehyde as a coupling agent will result in
protein binding 11-12 carbon atoms from the surface of the bead. Packaged as 2.5% solids (w/v)
aqueous suspensions. See Glutaraldehyde Kit with Hollow Fiber Filtering System, Cat. # 23964; also
see Glutaraldehyde Kit for Amino and Blue Dyed Microspheres, Cat. # 19540.

Polybead ® Carboxylate Microspheres A2dm
Polybead ® Carboxylate Microspheres are monodisperse polystyrene microspheres that contain surface
carboxyl groups. This allows for covalent binding of proteins to the bead surface. Packaged as
2.5% solids (w/v) aqueous suspensions. See PolyLink Protein Coupling Kit for Carboxylate Microspheres,
Cat. #24350.
