Brochure

Both Antibodix™ WCX and Proteomix® SCX phases are comprised of rigid, spherical, highly cross-linked non-porous poly(styrene divinylbenzene) (PS/DVB) beads. The PS/DVB particle surface is grafted with a highly hydrophilic, neutral polymer layer with a thickness in the range of nanometers. The hydrophobic PS/DVB resin surface is totally covered by a hydrophilic coating which eliminates non-specific bindings with antibody proteins, leading to high efficiency and high recovery separations.

Antibodix™ WCX phase
On top of the hydrophilic layer, weak cation-exchange carboxylate (-COOH) functional groups are attached via a proprietary chemistry, resulting in a high capacity ion-exchange layer.

Proteomix® SCX phase
On top of the hydrophilic layer, strong cation-exchange sulfonate (-SO₃H) functional groups are attached via a proprietary chemistry, resulting in a high capacity ion-exchange layer.
