Abstract: The invention relates to oligonucleotide probes attached to discrete particles wherein the particles can be grouped into a plurality of sets based on a physical property. A different probe is attached to the discrete particles of each set, and the identity of the probe is determined by identifying the discrete particles from their physical property. The physical property includes any that can be used to differentiate the discrete particles, and includes, for example, size, flourescence, radioactivity, electromagnetic charge, or absorbance, or label(s) may be attached to the particle such as a dye, a radionuclide, or an EML. In a preferred embodiment, discrete particles are separated by a flow cytometer which detects the size, charge, flourescence, or absorbance of the particle. The invention also relates to methods using the probes complexed with the discrete particles to analyze target nucleic acids.

Abstract: The invention relates to methods for preparing nucleic acid pools useful in hybridization studies. Such methods allow hybridization conditions, such as time, temperature, ionic strength, etc., to be adjusted to increase the likelihood that hybridization to the nucleic acids within each pool is within the linear range of detection (i.e., detectable but not saturating). The methods rely on pooling nucleic acids derived from a sample, based on the degree of representation within the sample, i.e., nucleic acids having similar degrees of representation within in a sample are combined into a pool. The invention also provides arrays and kits produced from pooled nucleic acids, and an improved method for identifying a nucleic acid and/or its representation in a sample.

Abstract: The conditions under which oligonucleotide probes hybridize preferentially with entirely complementary and homologous nucleic acid targets are described. Using these hybridization conditions, overlapping oligonucleotide probes associate with a target nucleic acid. Following washes, positive hybridization signals are used to assemble the sequence of a given nucleic acid fragment. Representative target nucleic acids are applied as dots. Up to 100,000 probes of the type (A,T,C,G)(A,T,C,G)N8(A,T,C,G) are used to determine sequence information by simultaneous hybridization with nucleic acid molecules bound to a filter. Additional hybridization conditions are provided that allow stringent hybridization of 6-10 nucleotide long oligomers which extends the utility of the invention. A computer process determines the information sequence of the target nucleic acid which can include targets with the complexity of mammalian genomes.
