Sepax Antibodix Columns

The packing support is composed of a rigid, spherical, highly cross-linked poly(styrene divinylbenzene) (PS/DVB) non-porous bead. The non-porous resin has particle size of 1.7, 3, 5 and 10 µm. The PS/DVB resin surface is grafted with a highly hydrophilic, neutral polymer thin layer with the thickness in the range of nanometer. On the top of the hydrophilic layer, weak cation-exchange functional groups are attached via a proprietary chemistry, resulting in high capacity ion-exchange layer.

• Highly cross-linked non-porous PS/DVB particle as the support
• Uniform particle size
• Particle size availability: 1.7, 3, 5, and 10 µm
• Weak-cation exchange chemistry
• Hydrophilic surface specially designed for elimination of non-specific bindings
• High separation efficiency, selectivity and resolving power
• High lot-to-lot reproducibility (link to below header)
• High loading capacity (link to below header)
• High recovery
• High mechanical stability with pressure tolerance higher than 8,000 psi for 5 and 10 µm, and 10,000 psi for 1.7 and 3 µm
• High pH stability: 2-12
• Well suited for UPLC and regular HPLC systems
• Complete selection for analytical, semi-preparative and preparative separations
• Applications for proteins, especially antibodies
