摘要:
Disclosed herein are methods, compositions and kits for quantitating one or more specific nucleic acids within a plurality of nucleic acids. In some embodiments, a sequencing library is constructed from enriched probe extension products specific for the specific nucleic acids and sequenced. In some embodiments, the resulting reads are used for removing duplicate reads. In some embodiments, counting of verified probes is used to quantitate or determine the number of specific nucleic acid molecules in the starting nucleic acid sample.
摘要:
Methods and compositions are provided related to the amplification of target polynucleotide sequences as well as total RNA and total DNA amplification. In some embodiments, the methods and compositions also allow for the immobilization and capture of target polynucleotides with defined 3' and or 5' sequences to solid surfaces. The polynucleotides attached to the solid surfaces can be amplified or eluted for downstream processing. In some cases, nucleotides attached to solid surfaces can be used for high throughput sequencing of nucleotide sequences related to target DNA or target RNA.
摘要:
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.
摘要:
The present invention provides novel composite primers. The composite primers are suitable for use in isothermal, single primer linear nucleic acid amplification methods, such as methods for amplifying complementary DNA using the composite primer, primer extension, strand displacement, and optionally a termination sequence or methods for amplifying sense RNA using a composite primer, primer extension, strand displacement, optionally template switching, a propromoter olignucleotide and transcription. The invention further provides compositions and kits comprising the composite primers.
摘要:
The invention provides methods for isothermal amplification of RNA. The methods are particularly suitable for amplifying a plurality of RNA species in a sample. The methods employ a composite primer, a second primer and strand displacement to generate multiple copies of DNA products comprising sequences complementary to an RNA sequence of interest. In another aspect, the methods employ a single primer (which is a composite primer) and strand displacement to generate multiple copies of DNA products comprising sequences complementary to an RNA sequence of interest. In some embodiments, a transcription step is included to generate multiple copies of sense RNA of an RNA sequence of interest. 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.
摘要:
Provided herein are methods, compositions and kits for targeted nucleic acid sequence enrichment in a nucleic acid sample and for high efficiency nucleic acid library generation for next generation sequencing (NGS). The methods, compositions and kits provided herein can be useful for the production and capture of amplification-ready, target-specific and strand-specific regions of interest from nucleic acid samples containing complex DNA.
