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. These microspheres are packaged as 2.5% solids (w/v) aqueous suspensions.

Nominal Reference Values:

• 0.50µm mean diameter
• 2.5% solids (w/v) aqueous suspension
• Coefficient of Variance (CV): 11%
