Abstract:
Ion exchange and hydrophobic interaction chromatographic materials are constructed by tethering a terminal binding functionality to a solid support via a hydrophobic linker. The backbone of the linker typically comprises sulfur-containing moieties. Suitable terminal binding functionalities are tertiary amines, quaternary ammonium salts, or hydrophobic groups. These chromatographic materials possess both hydrophobic and ionic character under the conditions prescribed for their use. The separation of proteins from crude mixtures at physiological ionic strength can be accomplished with a chromatographic material of this type by applying pH or ionic strength gradients, thereby effecting protein adsorption and desorption.
Abstract:

Abstract:
A hydrogel layer is applied to a substrate advantageously when the layer is formed in situ, using a polymeric or copolymeric precursor that includes, respectively, monomer subunits that have a photocrosslinkable functionality and monomer subunits that have a chemically selective functionality for binding a biomolecular analyte, such as a protein. A hydrogel-coated substrate thus obtained is particularly useful as a probe for mass spectroscopic analysis, including SELDI analysis. Hydrogel particles also can be used for SELDI analysis.
