Abstract: This disclosure provides chips, systems and methods for sequencing a nucleic acid sample. Tagged nucleotides are provided into a reaction chamber comprising a nanopore in a membrane. An individual tagged nucleotide of the tagged nucleotides can contain a tag coupled to a nucleotide, which tag is detectable with the aid of the nanopore. Next, an individual tagged nucleotide of the tagged nucleotides can be incorporated into a growing strand complementary to a single stranded nucleic acid molecule derived from the nucleic acid sample. With the aid of the nanopore, a tag associated with the individual tagged nucleotide can be detected upon incorporation of the individual tagged nucleotide. The tag can be detected with the aid of the nanopore when the tag is released from the nucleotide.

Abstract: The present technology relates generally to methods and compositions for targeted nucleic acid sequence enrichment, as well as uses of such enrichment for error-corrected nucleic acid sequencing applications. In some embodiments, highly accurate, error corrected and massively parallel sequencing of nucleic acid material is possible using a combination of uniquely labeled strands in a double-stranded nucleic acid complex in such a way that each strand can be informatically related to its complementary strand, but also distinguished from it following sequencing of each strand or an amplified product derived therefrom. In various embodiments, this information can be used for the purpose of error correction of the determined sequence.

Abstract: The present invention relates to a method for discriminating an operationally tolerant (TOL) subject from a non-operationally tolerant (STA) subject, comprising the following steps: i) establishing a composite score of tolerance (cSoT) with the expression levels of six genes in a biological sample obtained from said subject and two clinical parameters; wherein said six genes are ID3, AKR1C3, CD40, CTLA4, TCL1A and MZB1, and wherein said cSoT is established by the following formula: cSoT = ? i n ? = ? i × Exprs + ? test ? ? time × age test ? ? time + ? trans ? ? time × age trans ? ? time + intercept - scaling ? ? coefficient ii) comparing this cSoT with a predetermined reference value; and iii) concluding that the subject is TOL when the cSoT is higher than the predetermined reference value or concluding that the subject is STA when the cSoT is lower than the predetermined reference value.

Abstract: The present invention relates to a method for prenatal diagnosis using digital PCR, and more particularly to a method for providing information for diagnosis of chromosomal aneuploidy in a fetus, comprising: (a) extracting DNAs from pregnant woman's blood; (b) classifying the DNAs according to size to obtain DNAs having a size of 1,000 bp or less; (c) performing digital PCR using the obtained DNAs of step (b), for a control gene located on a chromosome not associated with chromosomal aneuploidy and a target gene located on a chromosome associated with chromosomal aneuploidy; (d) calculating a ratio of a quantitative digital PCR value of the target gene to a quantitative digital PCR value of the control gene; and (e) determining that when the ratio calculated in step (d) is 0.70-1.14, a chromosome number of the fetus is normal.

Abstract: The invention is directed to optically based methods for nanopore sequencing of polynucleotides which comprise steps of (i) translocating a polynucleotide through a bore of a nanopore at a translocation speed, wherein nucleotides of the polynucleotide are labeled with fluorescent labels such that in free solution fluorescent labels of nucleotides are substantially quenched and wherein fluorescent labels within the bore are constrained such that substantially no detectable fluorescent signal is generated therein; (ii) exciting the fluorescent label of each nucleotide upon exiting the nanopore and prior to quenching with a preceding mutually quenching fluorescent label or a quenching agent; (iii) measuring a fluorescent signal generated by fluorescent labels exiting the nanopore, wherein the translocation speed is selected so that the measured fluorescent signal comprises fluorescence from substantially a single fluorescent label; and (iv) determining a nucleotide sequence of the polynucleotide from a sequence

Abstract: This invention provides methods and systems for measuring the concentration of multiple nucleic acid sequences in a sample. The nucleic acid sequences in the sample are simultaneously amplified, for example, using polymerase chain reaction (PCR) in the presence of an array of nucleic acid probes. The amount of amplicon corresponding to the multiple nucleic acid sequences can be measured in real-time during or after each cycle using a real-time microarray. The measured amount of amplicon produced can be used to determine the original amount of the nucleic acid sequences in the sample.

Abstract: The invention provides methods and kits for ordering sequence information derived from one or more target polynucleotides. In one aspect, one or more tiers or levels of fragmentation and aliquoting are generated, after which sequence information is obtained from fragments in a final level or tier. Each fragment in such final tier is from a particular aliquot, which, in turn, is from a particular aliquot of a prior tier, and so on. For every fragment of an aliquot in the final tier, the aliquots from which it was derived at every prior tier is known, or can be discerned. Thus, identical sequences from overlapping fragments from different aliquots can be distinguished and grouped as being derived from the same or different fragments from prior tiers. When the fragments in the final tier are sequenced, overlapping sequence regions of fragments in different aliquots are used to register the fragments so that non-overlapping regions are ordered.
Abstract: The present invention provides compositions and methods based on genetic polymorphisms that are associated with cardiovascular diseases, particularly coronary heart disease (especially myocardial infarction) or hypertension.
