Abstract:
The present invention includes methods and compositions relating to locus-specific arrays. More specifically, this invention includes methods for making locus-specific arrays from universal arrays in situ, the custom arrays made using those methods, and methods of using the custom arrays to detect target nucleotides.
Abstract:
Methods for testing oligonucleotide arrays are disclosed including methods for testing the efficiency of nucleotide coupling; methods for testing amounts of deprotected oligonucleotides; methods for determining amounts of depurinated oligonucleotides; and methods of detecting the presence of cleavable structural features, such as double-stranded nucleic acids.
Abstract:
The invention provides methods for detecting variations in polymorphic sites and/or variations in gene copy number. The methods are particularly useful for analysis of biotransformation genes, such as cytochromes P450.
Abstract:
The invention provides arrays of polynucleotide probes having at least one pooled position. A typical array comprises a support having at least three discrete regions. A first region bears a pool of polynucleotide probes comprising first and second probes. A second region bears the first probe without the second probe and a third region bears the second probe without the first probe. A target nucleic acid having segments complementary to both the first and second probes shows stronger normalized binding to the first region than to the aggregate of binding to the second and third regions due to cooperative binding of pooled probes in the first region. The invention provide methods of using such arrays for e.g., linkage analysis, sequence analysis, and expression monitoring.

Abstract:
The invention provides nucleic acid segments of the glucose-6 phosphate dehydrogenase locus of the human genome including polymorphic sites. Allele-specific primers and probes hybridizing to regions flanking these sites are also provided. The nucleic acids, primers and probes are used in applications such as forensics, paternity testing, medicine and genetic analysis.
Abstract:
Methods and compositions are provided for performing a set of N DNA sequencing reaction cycles whereby sequence information is obtained for approximately 2*N nucleotide bases.
