Abstract:
An apparatus and system for contacting a mobile elongate solid phase, e.g. a ribbon with a flowing fluid phase, and a method for using the same in, for example solid phase synthesis. A particular apparatus comprises (i) a conduit which is of circular or non-circular transverse cross section and which defines a lumen to contain both the flowing fluid phase and the mobile elongate solid phase; (ii) fluid phase ports in communication with the lumen to allow the fluid phase to enter the lumen, flow through it and exit it; and (iii) solid phase ports in communication with the lumen to allow the mobile solid phase to enter the lumen, move through it and exit it, the apparatus being adapted to prevent fluid egress from its interior through the solid phase ports.Also provided is a continuous process for synthesising and screening molecules, comprising passing an elongate solid phase through successive treatment stations where different stages of a solid phase synthesis are performed, and screening the synthesised molecules for activity.

More specifically, the present invention relates to novel methods for the screening of the effects of a test compound on cells, for molecular analysis of the cells and for producing a microarray. The present invention also relates to cell arrays and the use of arrays for molecular analysis of the cells or for the screening of agents.
Abstract:
A process for making a micro-array. The process comprises the step of depositing a population of microbeads on a substrate having at least one fiducial. The population being comprised of at least two sub-populations, preferably multiple sub-populations, each comprising a known active agent capable of specific binding with at least one target analyte. The said subpopulations are deposited sequentially and at discrete periods of each other. The process also comprises the step of making images of the substrate after deposition of each subpopulation. The images are then compared using the fiducial as a reference to thereby determine the location of each microbead and to identify the subpopulation, and its known active agent, based on differences between each image. Also disclosed in a system for using the microarray.
Abstract:
The present invention provides novel arrays of oligonucleotide probes immobilized on a solid support in the form of a chip (millichip), which can be used for rapid and inexpensive analysis of nucleic acids. The arrays can have a plurality of different oligonucleotide probes that can provide for whole genome gene expression analysis. The millichip can be used for analysis of both RNA and DNA.

Abstract:
The present invention relates to a peptide nucleic acid (PNA) conjugated with multi-amine linkers, and a method to prepare the same and utilization thereof. More specifically, the method is characterized by conjugating monomers having multi-amine functionality sequentially at a PNA terminal, and effectively immobilizing the PNA conjugated with multi-amine linkers on a solid surface. A PNA array prepared using the PNA conjugated with multi-amine linkers exhibits improved sensitivity and specificity of signals for detecting target nucleic acids as compared to a PNA array using PNA probes having only one amine group. The PNA conjugated with multi-amine linkers can be utilized in nucleic acid detecting devices or kits for gene diagnosis such as PNA microarrays, PNA chips, PNA field-effect transistors and impedance detectors.
Abstract:
A method for preferentially localizing desired molecules within an optical confinement disposed upon a substrate is disclosed. The desired molecules are deposited over the surface of the substrate. The desired molecules that are not within the optical confinement are selectively removed from the surface of the substrate.
Abstract:
A method of selecting a set of normalization probes for use on a comparative genome hybridization array is provided. In certain embodiments, the method includes: a) selecting a first region of a genome to be evaluated by comparative genome hybridization to produce data; b) selecting a second region of the genome for normalization of the data, and c) selecting from a set of candidate probes a sub-set of normalization probes that detect the second region.
