摘要： Disclosed are pellicular materials useful in contact with proteins and as chromatography media. Rigid, inert, hydrophobic, polymeric materials are exposed to a solution comprising a solute defining plural interspersed hydrophobic and hydrophilic domains. The solute molecules adsorb onto the surface of the substrate by hydrophobic - hydrophobic interaction with their hydrophilic domains extending outwardly away from the surface into the solution. The molecules are then crosslinked in place to produce a solvent and pH resistant coating which presents a hydrophilic surface sufficient to mask hydrophobic regions therebeneath. The multidomain adsorbing compounds may comprise reactive groups which subsequently can be derivatized using conventional techniques to produce chromatography materials useful for conducting affinity, size exclusion, cationic exchange, anionic exchange, neutral hydrophobic interaction, and other forms of chromatographic separations.

摘要： Disclosed are specifically designed binding, "protein imaged" sorbents which reversibly bind with high specificity and affinity a preselected macromolecule, specifically a protein. The sorbents define one or more cavities which have a binding surface complementary in shape to the molecular surface of the macromolecule and a plurality of positively and negatively charged chemical moieties spatially distributed in a mirror image and charge inverse of a subset of the ionizable groups on the molecular surface of the macromolecule. Also disclosed are methods of producing such sorbents, useful over a range of conditions, for both preparative and analytical chromatographic separations or for use in various types of analyses.

摘要： A diagnostic method for determining the absence or presence of a disease is provided. The method generally includes assaying the amount and/or types of oxidized peptides in a sample from a subject, and comparing these to the amount and types of reference oxidized polypeptides. The method may include the use of stable isotope label, affinity selection, to identify and quantify changes in oxidized peptides or oxidized proteins associated with diseases such as type II diabetes mellitus, breast cancer, and Parkinson's disease, to monitor a patient's response to a therapeutic agent (e.g., an antioxidant), and/or to monitor disease recurrence.

摘要： A multi-dimensional method for simultaneously analyzing multiple analytes within a sample solution, comprising adding affinity selectors to a sample solution containing analytes to be measured, the affinity selectors having an affinity for one or more of the analytes within the sample solution; allowing immune complexes to form between the affinity selectors and the analytes; partially or totally resolving the formed immune complexes from non-analyte substances within the sample solution; dissociating the resolved immune complexes; separating the analytes and the affinity selectors of the dissociated immune complexes from one another by capturing the analytes through a surface adsorption process; transferring the captured analytes to a detection means; and resolving the analytes with the detection means in accordance with their mass-to-charge ratios.

摘要： A device for identifying analytes in a biological sample, including a substrate having a surface lying substantially in a first plane, a plurality of targets, each having a wall lying substantially in a second plane offset from the first plane, and a receptor coating applied to one of the surface and the target walls for binding analytes present in the biological sample when the biological sample is applied to the substrate. A laser beam is sequentially directed onto each of the plurality of target, the laser being positioned relative to the substrate such that when the beam is directed onto a target, a first half of the beam is reflected back to the laser from the wall of the target and a second half of the beam is reflected back to the laser from the surface of the substrate adjacent the target. The laser combines the first and second reflected halves to produce a diffraction signal that has a first value when an analyte is not bound to the receptor coating associated with a target and a second value when an analyte is bound to the receptor coating associated with the target, thereby indicating the presence of the analyte.

摘要： Disclosed are chromatography methods and matrix geometries which permit high resolution, high productivity separation of mixtures of solutes, particularly biological materials. The method involves passing fluids through specially designed chromatography matrices at high flow rates. The matrices define first and second interconnected sets of pores and a high surface area for solute interaction in fluid communication with the members of the second set of pores. The first and second sets of pores are embodied, for example, as the interstices among particles and throughpores within the particles. The pores are dimensioned such that, at achievable high fluid flow rates, convective flow occurs in both pore sets, and the convective flow rate exceeds the rate of solute diffusion in the second pore set. This approach couples convective and diffusive mass transport to and from the active surface and permits increases in fluid velocity without the normally expected bandspreading.
