    摘要: Methods for determining the amount of an RNA transcript in a test sample are disclosed, utilizing a reference sample comprising a known amount of a reference nucleic acid, labeled with a first strand 3′ cDNA primer and a first strand 5′ cDNA primer comprising a reference specificity determining box; and a test sample comprising an amount of test RNA containing an RNA transcript of interest, the test RNA being labeled with the first strand 3′ cDNA primer and a first strand 5′ cDNA primer comprising a test specificity determining box. The reference sample and the test sample are mixed and subjected to polymerase chain reaction amplification conditions, followed by division of the amplified, mixed sample and continued amplification of the divided sample to produce nucleic acids containing amplified reference nucleic acid or amplified cDNA of the test RNA, from which cRNA can be generated by in vitro transcription. The amount of the test RNA, or of the RNA transcript of interest, in the sample correlates with a ratio of the amount of amplified cDNA of the test RNA (or of the RNA transcript of interest), over the amount of the amplified reference nucleic acid, multiplied by the known amount of the reference nucleic acid in the reference sample.

    摘要: The invention provides methods for determining the activity of a plurality of nucleic acid regulatory elements. These methods may facilitate, e.g., the systematic reverse engineering, and optimization of mammalian cis-regulatory elements at high resolution and at a large scale. The method may include integration of multiplexed DNA synthesis and sequencing technologies to generate and quantify the transcriptional regulatory activity of e.g., thousands of arbitrary DNA sequences in parallel in cell-based as says (e.g., mammalian cell based assays).

    摘要: The invention provides nucleic acid segments of the human genome, particularly nucleic acid segments from a gene, including polymorphic sites. Allele-specific primers and probes hybridizing to regions flanking or containing these sites are also provided. The nucleic acids, primers and probes are used in applications such as phenotype correlations, forensics, paternity testing, medicine and genetic analysis. A role for the thrombospondin gene(s) in vascular disease is also disclosed. Use of single nucleotide polymorphisms in the thrombospondin gene(s) for diagnosis, prediction of clinical course and treatment response, development of therapeutics and development of cell-culture-based and animal models for research and treatment are disclosed.
