Proteomix IEX
Non-porous Proteomix Ion-exchange Phases - High Resolution and High Capacity
Sepax Technologies
Description
Proteomix ion-exchange phases have been innovatively developed for achieving high ion-exchange capacity, a breakthrough technology for non-porous resins. Proteomix packing support is composed of a rigid, spherical, highly cross-linked poly(styrene divinylbenzene) (PS/DVB) non-porous bead with particle size selections 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. The hydrophobic PS/DVB resin surface is totally covered by a hydrophilic coating that eliminates non-specific bindings with biological analytes, leading to high efficiency and high recovery separations for biological molecules. On the top of the hydrophilic layer, ion-exchange functional groups are attached via a proprietary chemistry, resulting in a high capacity ion-exchange layer.
- Uniform polymer beads as the packing support
- Proprietary surface chemistry specially designed for elimination of non-specific bindings
- Tunable separation capacity with combination of the pore structure and the controllable surface chemistry
- Unprecedented separation efficiency, selectivity and resolving power
- Complete selection for analytical, semi-preparative and preparative separations
- Wide particle size selection
- High stability
- High recovery
- High lot-to-lot reproducibility
- Well suited for UPLC system
