Abstract: The present invention relates to an improved apparatus and method for assembly for a cylindrical split-flow thin separation channel that is capable of continuously separating particles of interest from a suspension flowing through the channel. The apparatus provides better precision in the separation process by providing better flow characteristics at the inlet, outlet, and in the zone of separation. Splitter surfaces are provided that match the calculated theoretical Inlet Splitter Surface (ISS) and Outlet Splitter Surface (OSS). A flow distributor diverts the inlet carrier flow into a stable, circumferentially uniform, laminar annular flow. The design enables manufacturing and assembly methods to ensure precise alignment of the components to further improve the flow profiles within the separation channel and to ensure repeatability device-to-device.

Abstract: The present invention provides a fast and efficient method for determining the three-dimensional conformation of a protein. The steps of the method of the invention include: 1) formation of physical distance constraints, e.g., forming intramolecular chemical crosslinks of known size between residues of a protein; 2) enriching the number of the molecules that have intramolecular chemical crosslinks in the reaction pool, e.g., using size separation to remove proteins with intermolecular bonds; 3) exposing the enriched reaction pool to a protease that cuts the protein at specific sites to produce peptide fragments; 4) measuring the size of the peptide fragments to determine linkage sites with a certain spatial relationship in the protein; and 5)interpreting the data produced to determine spatial geometry and protein structure based on the deduced spatial relationship of the linkage sites.

Abstract: A purified glycoprotein complex of over 1200 kD apparent native molecular weight having a sedimentation value of approtely 25S and having the ability to selectively bind human Mac-2 or interfere with PHA activation of lymphocytes, DNA sequences that encode the protein, and expression systems for expressing it, thus providing for medicaments that are useful for treating or diagnosing diseases, including cancer, infectious disease, and diseases of the immune system.

Abstract: A method for analyzing the ADME/PK properties of a mixture of compounds is (1) perfusing an animal or organ with a perfluorocarbon emulsion blood substitute, (2) administering the mixture of test compounds, (3) withdrawing an aliquot of the perfusate, (4) disrupting the emulsion, and (5) analyzing the aqueous phase of the perfusate for the concentration of test compounds.
