  • Publication number: 20070048756
    Abstract: Methods for determining the genotype of more than 400,000 Single Nucleotide Polymorphisms (SNPs) in samples of genomic DNA are provided. A collection of SNPs that may be interrogated by the methods is disclosed in SEQ ID NO: 1-1,074,930. Each sequence is the sequence of a human SNP allele and the 16 bases flanking the SNP on either side. A sequence for each allele is included. In some aspects arrays of probes to interrogate the genotype of a collection of SNPs are disclosed. In preferred aspects the probes are 17 or more contiguous nucleotides from a sequence in SEQ ID NO: 1-1,074,930 or its complement.

  • Patent number: 7053206
    Abstract: A method is described for predetermining ratios of primer pairs present in a single reaction vessel so as to achieve approximately equimolar yield of products. The ratios are determined as a function of the length of the amplicon and the length of other amplicons being simultaneously tested. The primers may desirably be for p53 gene sequences.

  • Publication number: 20050191646
    Abstract: The present invention provides a simplified method for identifying differences in nucleic acid abundances (e.g., expression levels) between two or more samples. The methods involve providing an array containing a large number (e.g. greater than 1,000) of arbitrarily selected different oligonucleotide probes where the sequence and location of each different probe is known. Nucleic acid samples (e.g. mRNA) from two or more samples are hybridized to the probe arrays and the pattern of hybridization is detected. Differences in the hybridization patterns between the samples indicates differences in expression of various genes between those samples. This invention also provides a method of end-labeling a nucleic acid. In one embodiment, the method involves providing a nucleic acid, providing a labeled oligonucleotide and then enzymatically ligating the oligonucleotide to the nucleic acid. Thus, for example, where the nucleic acid is an RNA, a labeled oligoribonucleotide can be ligated using an RNA ligase.
