Abstract:
The present invention provides methods and kits for purifying a target protein group. The method comprises the steps of contacting a sample comprising at least 95% of the target protein group and at most 5% of contaminating proteins with a library of binding moieties having different binding moieties, binding the contaminating proteins and a minority of the target protein group to the library of binding moieties, separating the unbound target protein group from the proteins bound to the library of binding moieties and collecting the unbound target protein. The collected target protein is more pure than the target protein group in the sample.
Abstract:
The present invention provides a facile and efficient method for determining a chromatographic protocol for separating a target protein from one or more second protein impurity. Also provided is a database facilitating the determination of an appropriate separation protocol.

Abstract:
The present invention relates to injectable compositions comprising biocompatible, hydrophilic, non-toxic and substantially spherical microspheres associated with stem cells useful for tissue construction and generation. The invention also relates to methods of tissue construction and generation, for the treatment of various tissue damage and defects, using the injectable compositions.
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.

Abstract:
Materials, apparatuses, methods, and systems for isolating and identifying mixture components on the basis of isoelectric point (“pI”). In one aspect, the materials are particles adapted to have a predetermined isoelectric point. The particles include a porous body into which a plurality of cavities extend. A substance of a predetermined isoelectric point is deposited in the cavities to provide thereby the particle's isoelectric value.
