资料摘要:
The Proteomix ion-exchange columns are specially designed for high resolution, high efficiency and high recovery separations of proteins, oligonucleotides, carbohydrates, and peptides. The packing support is composed of a rigid, spherical, highly cross-linked poly(styrene divinylbenzene) (PS/DVB) bead. Both porous and non-porous PS/DVB beads are provided. The porous PS/DVB resin has particle size of 5 and 10 µm with the pore size of 500 Å. The non-porous resin has particle size of 1.0, 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 such a hydrophilic coating that eliminates non-specific bindings with biological analytes, leading to high efficiency and high recovery separations for biomolecules. On the top of the hydrophilic layer, an ion-exchange functional group is attached via chemical bonding. A proprietary chemistry was developed to synthesize a densely packed and uniform ion-exchange layer.
