  • Publication number: 20090221430
    Abstract: The invention relates to methods for detecting and identifying potential biomarkers of high-grade cervical dysplasia in an individual human subject. The invention also relates to newly discovered biomarkers, as set forth in Tables 1-4 herein, which are associated with the dysplastic state of cervical cells. It has been discovered that a differential level of expression of any of these markers or combination of these markers correlates with a dysplastic condition in a human subject, e.g., a patient.

  • Publication number: 20090035797
    Abstract: Described herein are methods and techniques to study the “degradome”. The degradome of a specific protease is the complete product of the natural substrate repertoire of that enzyme in a cell, tissue or organism. The complete set of proteases that are expressed at a particular moment or circumstance by a cell, tissue or organism produces the collective degradome. Included in the methods described herein are approaches that allow the direct identification and characterization of degradome peptides from approx. 400 to approx. 12,000 Da. The methods of the invention avoid the inherent problems of studying the peptidome by focusing on specific or unique proteolytic cleavages that occur as a result of endogenous protease activity induced by specific diseases. Once characterized, the presence of, or change in level of, specific peptides of the degradome can be used, e.g.

  • Publication number: 20080280317
    Abstract: A combination of “bottom up” and “top down” MS analysis of posttranslational modifications in complex proteins is described. The method comprises digestion of the protein with an enzyme that forms larger peptide fragments than trypsin (>3000 D), performing HPLC with the fragments and applying a new data acquisition strategy using on-line coupling with e.g. LTQ-FTMS, a hybrid mass spectrometer that couples a linear ion trap with a Fourier transform ion cyclotron resonance (FTICR) cell. The method is applied to analysis of posttranslational modifications of protein isoforms.

  • Patent number: 6107038
    Abstract: An electrophoretic technique is provided for moving a plurality of chemicals into distinct zones for immobilization on a solid surface. The technique includes introducing a first electrolyte and a second electrolyte into a channel, and interposing between the first and second electrolytes at least one solution containing a plurality of chemicals. Under a given electric field, the first electrolyte has anions with higher effective mobility than the chemicals and the second electrolyte has anions with lower effective mobility than the chemicals. When an electrical potential is applied across the length of the channel the plurality of chemicals in the solution are moved into spatial zones. The chemicals in the zones can then be bound to the interior surface of the channel. Chemicals so bound to the wall surface can be used to build very small structures such as arrays and electrical conducting structures.

  • Patent number: 5614487
    Abstract: The present document discloses the formation of imine adducts, preferably between a primary amine of a biologically active polypeptide and a reactive aldehyde group of a physiologically acceptable carrier. The imine adduct of human growth hormone and dextran is specifically described. These adducts serve to release the biologically active polypeptide via the reversible reaction in the formation of the imine adduct bond. These adducts have a surprising degree of stability that permits the use of the complex as a sustained release preparation. A key advantage of this technology is that after hydrolysis the complex releases the unmodified pharmaceutical. Thus, these adducts can be used as pharmaceutical compositions useful for the sustained release of the biologically active polypeptide over a predetermined, desired period of time.

  • Patent number: 4909941
    Abstract: There is described a mobile phase for use in the purification of proteins using reversed phase HPLC on a preparative scale. The mobile phase is an aqueous solution containing 0.005 to 1M of a physiologicially acceptable acid of the general formula YCOOH where Y is a polar electron withdrawing group capable of hydrogen bonding silanol groups. The solution also contains up to 95% by volume of a physilogically acceptable organic solvent. A preparative method of purifying proteins such as HSA or BSA and recombinant deoxyribonucleic proteins using reversed phased PHLC is also described.

  • Patent number: 4603010
    Abstract: A process is described for removing low density and very low density lipoproteins from blood plasma or serum and recovering the plasma or serum in a physiologically acceptable form. The method involves in a preferred embodiment passing plasma or serum through a cationic ion exchanger equilibrated with a physiologically acceptable saline solution. The ion exchanger is a water insoluble hydrophilic, water swellable cross-linked regenerated or microgranular cellulose matrix substituted with hydroxy C.sub.2 -C.sub.4 alkyl group. The ion exchanger capacity is provided by sulphate groups substituted with from 2 to 6 meq/g. The take up of low density lipoproteins is enhanced by recycling the plasma through the column.
