Sepax Technologies Inc Sepax HPLC Column Proteomix SCX, NP3, Guard cartridge (No Holder), 2 x 10 mm
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.
