Abstract: The invention provides a microarray and methods for producing a protein microarray. The array comprises multiple nucleic acid molecules immobilized on a substrate, each comprising (i) a protein-binding domain and (ii) a nucleic acid sequence encoding a fusion protein comprising a polypeptide of interest and a DNA-binding protein that binds the protein-binding domain, and one or more fusion proteins produced from the multiple nucleic acid molecules. Each fusion protein is immobilized on the substrate via binding to a nucleic acid sequence comprising the protein-binding domain present on the nucleic acid molecule from which the fusion protein is produced or on the substrate. The invention also provides a method of analyzing protein interactions with, for example, other proteins, lipids and drugs.

Abstract: The present invention relates generally to methods of detecting and identifying known and unknown viruses using hybridization microarrays to essentially all known influenza virus nucleotide sequences of at least one type that infect at least one species, the sequencing of nucleotides which hybridize to the microarrays and analysis of the hybridized sequences with existing databases, thus identifying existing or new subtypes of viruses. The present invention also relates to methods of use of the microarrays of the invention for the detection of influenza viruses, including variant influenza viruses. The method includes the use of a non-specific PCR amplification method to amplify sample nucleic acids.

Abstract: A method for amplifying a nucleic acid fragment is described. A nucleic acid having interspersed repetitive elements is cleaved and the resulting nucleic acid fragments are ligated to a bubble oligonucleotide having two double stranded portions flanking a non-complementary portion consisting of two single strands to make bubble/nucleic acid units. These units are treated with a first primer that is complementary to at least a portion of the interspersed repetitive element, and with a second primer that is complementary to at least a portion of the extension product of the first primer, that portion containing sequences complementary to one of the single strands of the bubble oligonucleotide, under conditions which produce extension products of the primers. Also described are methods for labeling the products of the amplification, methods for detecting chromosomal aberrations and other uses of the amplification products.
