    摘要: A microflow apparatus for separating or isolating cells from a bodily fluid or other liquid sample uses a flow path where straight-line flow is interrupted by a pattern of transverse posts. The posts are spaced across the width of a collection region in the flow path, extending between the upper and lower surfaces thereof; they have rectilinear surfaces, have arcuate cross-sections, and are randomly arranged so as to disrupt streamlined flow. Sequestering agents, such as Abs, are attached to all surfaces in the collection region via a hydrophilic coating, preferably a hydrogel containing isocyanate moieties or a PEG or polyglycine of substantial length, and are highly effective in capturing cells or other targeted biomolecules as a result of such streamlined flow disruption.

    摘要: A versatile reagent with a non-nucleotide monomeric unit having a ligand, and first and second coupling groups which are linked to the non-nucleotide monomeric unit. The ligand can be either a chemical moiety, such as a label or intercalator, or a linking arm which can be linked to such a moiety. Such reagent permits preparation of versatile nucleotide/non-nucleotide polymers, having any desired sequence of nucleotide and non-nucleotide monomeric units, each of the latter of which bear a desired ligand. These polymers can for example, be used as probes which can exhibit enhanced sensitivity and/or which are capable of detecting a genus of nucleotides each species of which has a common target nucleotide sequence of interest bridged by different sequences not of interest.

    摘要: A composition suitable for sulfurizing an organophosphite. The reagent comprises a solution of sulfur and a tertiary amine, in a suitable solvent such as carbon disulfide. The tertiary amine is preferably an optionally substituted trialkyl amine, for example triethylamine or diisopropylamine. A method is also provided in which phosphites or phosphonous esters are sulfurized to their corresponding phosphorothioates or phosphonothioates, respectively, using compositions of the present invention. This method has particular application to produce internucleotide phosphorothioate or phosphonothioate bonds in a nucleotide multimer.

    摘要: A micro flow device (11, 71) for separating or isolating cells from a bodily fluid or other liquid sample uses a flow path where straight-line flow is interrupted by a pattern of transverse posts (23, 81). The posts are spaced across the width of an expanded collection chamber region (17, 75) in the flow path, extending between the upper and lower surfaces thereof; they have rectilinear surfaces, being curved in cross-sections, e.g. circular or tear-drop shaped, and are randomly arranged so as to disrupt streamlined flow. The device is oriented so that its lower surface is aligned at about 45° to the horizontal. Sequestering agents, such as Abs, which are attached to surfaces of the collection region via a hydrophilic coating, preferably a permeable hydrogel containing isocyanate moieties, are highly effective in capturing cells or other targeted biomolecules while the remainder of the liquid sample exits horizontally.

    摘要: Spheroidal beads present an exterior surface of a hydrophilic hydrogel, which is an isocyanate-functional polymer that is polymerized by urethane bonds and cross-linked by urethane and urea bonds. Sequestering agents present at the surface are covalently bound to isocyanate groups or to intermediate linkers that are so bound. These beads allow sequestering agents to retain their native three-dimensional configuration, and as a result of such surface characteristics and hydrophilicity, they achieve highly effective capture of very small subpopulations of rare cells from bodily fluids or the like and very effectively deter nonspecific binding of other biomaterials present in such bodily fluid. They may be all-hydrogel spheroids or hydrogel-coated substrates.
