The present invention provides methods, compositions and kits for the generation of next generation sequencing (NGS) libraries in which non-desired polynucleotides have been depleted or substantially reduced. The methods, compositions and kits provided herein are useful, for example, for the production of libraries from total RNA with reduced ribosomal RNA and for the reduction of common mRNA species in expression profiling from mixed samples where the mRNAs of interest are present at low levels. The methods of the invention can be employed for the elimination of non-desired polynucleotides in a sequence-specific manner, and consequently, for the enrichment of nucleic acid sequences of interest in a nucleic acid library.


Provided herein are methods, compositions and kits for the generation of bisulfite-converted next generation sequencing (NGS) libraries. The methods, compositions and kits provided herein can be useful, for example, for the production of libraries from genomic DNA that allow for determination of the methylation status across the genome, i.e. the methylome. The methods, compositions and kits provided herein can also be utilized to query methylation status at a particular genomic locus or loci. Moreover, the methods provided herein can be employed for high-throughput sequencing of bisulfite-converted DNA while maintaining the directional (strandedness) information of the original nucleic acid sample.

Described herein are methods, compositions and kits for the generation of bisulfite-converted libraries useful for conducting reduced representation bisulfite sequencing (RRBS). The methods described herein can be employed to generate RRBS libraries in a manner that is easier and more cost-efficient than conventional RRBS methods, and can be efficiently sequenced with next generation sequencing (NGS) techniques without the need for genomic, higher diversity sequencing controls such as PhiX spike-ins.


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.

Described herein are improved methods, compositions and kits for next generation sequencing (NGS). The methods, compositions and kits described herein enable phasing of two or more nucleic acid sequences in a sample, i.e. determining whether the nucleic acid sequences (which can comprise regions of sequence variation) are located on the same chromosome and/or the same chromosomal fragment. Phasing information can be obtained by performing multiple, successive sequencing reactions from the same immobilized nucleic acid template. The methods, compositions and kits provided herein can be useful, for example, for haplotyping, SNP phasing, or for determining downstream exons in RNA-seq.


Patent
NuGEN Technologies | Date: 2016-01-07

The present invention provides improved methods, compositions and kits for short read next generation sequencing (NGS). The methods, compositions and kits of the present invention enable phasing of two or more nucleic acid sequences in a sample, i.e. determining whether the nucleic acid sequences (typically comprising regions of sequence variation) are located on the same chromosome and/or the same chromosomal fragment. Phasing information is obtained by performing multiple, successive sequencing reactions from the same immobilized nucleic acid template. The methods, compositions and kits provided herein are useful, for example, for haplotyping, SNP phasing, or for determining downstream exons in RNA-seq.


Patent
NuGEN Technologies | Date: 2015-08-06

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.
