Abstract: A method is disclosed which relates to the placement of binding partners on microarrays, where such binding partners contain proteins, nucleic acids, biological cells and other bio-reactive components. The present invention discloses uses and methods for manufacture of microarrays constructed in part by sectioning bundles of tubules or rods containing matrix immobilized bio-reactive molecules to produce large numbers of sample chips. The chips so produced are processed by deposition to microarrays. The deposited chips can then be manipulated to partition the immobilizing matrix away from the bio-reactive molecules contained in the matrix and to place said partitioned molecules onto various surfaces for subsequent analysis, to include binding assays, hybridization reactions, diagnostic methods and a variety of cell interaction-determining methodologies.

Abstract: A method for separating microorganisms, especially infectious agents, from a mixture by two dimensional centrifugation on the basis of sedimentation rate and isopycnic banding density, for sedimenting such microorganisms through zones of immobilized reagents to which they are resistant, for detecting banded particles by light scatter or fluorescence using nucleic acid specific dyes, and for recovering the banded particles in very small volumes for characterization by mass spectrometry of viral protein subunits and intact viral particles, and by fluorescence flow cytometric determination of both nucleic acid mass and the masses of fragments produced by restriction enzymes. The method is based on the discovery that individual microorganisms, such as bacterial and viral species, are each physically relatively homogeneous, and are distinguishable in their biophysical properties from other biological particles, and from non-biological particles found in nature.

Abstract: A rotating processor is disclosed. The apparatus includes a hollow enclosed rotor, a rotor drive, internal space to hold particulate porous reaction or separations media which may be porous, lines connecting the center and periphera of the internal space with the exterior through fluid line seals, valving to control fluid flow, gradient makers, and a microprocessor to control and monitor the entire system. Optionally the rotor may be spun with the axis vertical or horizontal, and may be used as a conventional column at rest. The rotating processor permits any synthetic or separative process utilizing particulate or solid phase supports or separations involving phases of different density to be accomplished under conditions which facilitate precise control of fluid flow and minimization of both micro- and macro-anomalous flow. A computer-controlled flat multiport valve system is also described to facilitate programmed scheduling of reagents through the rotor.
