Abstract:
The present invention contemplates various devices that are configured to separate a sample, which contains more than one unique species, into any desired number of sub-samples by passing the sample across a like number of separation media configured for a first separation protocol. Each of the sub-samples may be further separated by an additional separation protocol, thereby creating a plurality of mini-samples, each of which may be further separated and/or analyzed. The invention also contemplates using a simple method of using conduits to form a fluid path that passes through a plurality of separation media, each of which media is configured to isolate a particular sub-sample. After various sub-samples of the sample are isolated by the various separation media, the conduits may be removed, thereby enabling each of the isolated sub-samples to be further separated and/or analyzed independent of any other sub-sample.

Abstract:
In relation to a chromatographic chip, for protein separation, a polymer surface is provided that has a first polymer layer, attached to a support surface, which can be anionic or cationic. To the first layer is attached a second polymer layer, characterized by an opposite charge.
Abstract:
Proteins can be separated from mixtures, based on their pI values, through the use of a series of chromatographic materials, each comprising a solid buffer and an ion exchange resin. Each solid buffer generates a stable pH, such that passing proteins possess a net charge and can be separated by means of an appropriate ion exchanger. In this fashion, proteins from complex biological fluids can be separated for identification and study.
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:
This invention relates generally to modified porous solid chromatographic media and processes for the preparation and use of same. In particular, chromatographic media of porous mineral oxide, polymeric, or polymer-coated mineral oxide supports are disclosed which are characterized by a reversible high sorptive capacity and high intraparticle mass transfer rates. In order to prevent non-specific adsorption of or interaction with biomolecules, these supports may be passivated by use of a passivation mixture comprising a main monomer, a passivating monomer, and a crosslinking agent, which mixture upon polymerization results in substantial elimination of the undesirable non-specific interaction with biomolecules.
