| 20120045797 | NUCLEIC ACID AMPLIFICATION PROCEDURE - The invention provides methods for amplification of polynucleotide sequences using primers containing single-Cstranded RNA. The methods employ use of an enzyme capable of cleaving single-stranded RNA, such as RNase I, to degrade a first RNA-containing primer prior to addition of a second RNA-containing primer. The invention also provides compositions and kits pl. for practicing the amplification methods, as well as methods which use the amplification products. | 02-23-2012 |
| 20110319290 | Methods and Compositions for Multiplex Sequencing - Adapters are joined to target polynucleotides to create adapter-tagged polynucleotides. Adapter-tagged polynucleotides are sequenced simultaneously and sample sources are identified on the basis of barcode sequences. | 12-29-2011 |
| 20110294132 | Method for Archiving and Clonal Expansion - The present method provides methods, libraries, and kits related to the archiving and clonal expansion of sequences related to target polynucleotide sequences. The method allow for the attachment of polynucleotides with defined 3′ and or 5′ sequences to solid surfaces. The polynucleotides attached to the solid substrates can be stored or archived as libraries and can subsequently be retrieved for analysis, for example by clonal expansion. In some embodiments, nucleotides attached to solid surfaces can be used for sequencing of nucleotide sequences related to target RNA or target RNA. The methods are applicable to total RNA and/or total DNA analysis. | 12-01-2011 |
| 20110224105 | METHODS, COMPOSITIONS, AND KITS FOR GENERATING NUCLEIC ACID PRODUCTS SUBSTANTIALLY FREE OF TEMPLATE NUCLEIC ACID - Methods, kits, and compositions are provided herein for the generation of double stranded DNA products suitable for downstream analysis. | 09-15-2011 |
| 20110189679 | COMPOSITIONS AND METHODS FOR WHOLE TRANSCRIPTOME ANALYSIS - The present invention provides methods and compositions, including kits, for the generation of cDNA from mRNA with reduced ribosomal RNA representation. | 08-04-2011 |
| 20110105364 | COMPOSITIONS AND METHODS FOR TARGETED NUCLEIC ACID SEQUENCE SELECTION AND AMPLIFICATION - The present invention provides novel methods, compositions, and kits for the production of amplification-ready, sequence-specific, target region-specific, and strand-specific regions of interest directly from samples containing complex DNA. The methods, composition, and kits provided herein are useful for selective target generation, genome partitioning, or user-selected enrichment of desired regions of interest. The invention described herein will enable multiplexing for genome-wide analysis with increased efficiency and is amenable to automation. | 05-05-2011 |
| 20100311066 | METHODS AND COMPOSITIONS FOR GENERATION OF MULTIPLE COPIES OF NUCLEIC ACID SEQUENCES AND METHODS OF DETECTION THEREOF - The present invention provides novel isothermal methods of generating multiple copies of, detecting and/or quantifying nucleic acid sequences of interest based on limited primer extension or attachment of oligonucleotide pairs using composite RNA/DNA primers. Methods for generating multiple copies of and/or detecting and/or quantifying nucleic acid sequences, wherein products of primer extension or attachment of oligonucleotide pairs comprising a cleavable portion are generated, and wherein cleavage of the products results in dissociation of cleaved products from target polynucleotides, are provided. The invention further provides compositions, kits and systems for practicing these methods. | 12-09-2010 |
| 20090239232 | METHODS OF RNA AMPLIFICATION IN THE PRESENCE OF DNA - The invention provides methods for amplification of RNA. The methods are particularly suitable for specifically amplifying RNA in the presence of DNA. The methods involve producing a marked first primer extension product from a target RNA in the presence of a DNA-dependent DNA polymerase inhibitor, which prevents replication of DNA by the reverse transcriptase enzyme. The marked nucleic acid products are subsequently selectively amplified in the presence on non-marked nucleic acids. The methods are useful for production and analysis of polynucleotide sequences complementary to an RNA sequence. The methods are useful for preparation of nucleic acid libraries and substrates for analysis of gene expression of cells in biological samples. The invention also provides compositions and kits for practicing the amplification methods, as well as methods which use the amplification products. | 09-24-2009 |
