20150376697 | METHOD AND SYSTEM TO DETERMINE BIOMARKERS RELATED TO ABNORMAL CONDITION - A method and system to determine biomarkers related to abnormal condition in a subject are provided, comprising:sequencing nucleic acid samples from a first and a second subject in order to obtain multiple sequences respectively consisting of the first and the second sequencing results, wherein the first subject is in the abnormal condition; and the second subject is not in the abnormal condition; and the nucleic acid samples from the first and the second subject are both isolated from the samples of the same type; and the first and the second subject belong to the same species; and determining the biomarkers related to the abnormal condition in the subject based on the difference between the first and the second sequencing results. | 12-31-2015 |
20150242565 | METHOD AND DEVICE FOR ANALYZING MICROBIAL COMMUNITY COMPOSITION - The present teachings relate to analysis of a sample including a plurality of species. In one example, sequences of fragments of polynucleotides of the sample are obtained. A reference set comprising a plurality of sequences is obtained. An initial bin for each of the plurality of sequences of the reference set is determined based on a relative abundance of each sequence of the reference set in the sample. At least one final bin is obtained by modifying the initial bins for the plurality of sequences based on a model. | 08-27-2015 |
20140296084 | Method for preparing nucleic acid library, its uses and kits - Provided are a method of constructing a nucleic acid library, a method of determining a nucleic acid sequence of a nucleic acid sample, and a kit thereof. The method of constructing the nucleic acid library includes the following steps: subjecting a nucleic acid sample to a DOP-PCR amplification, to obtain a first PCR amplification product; subjecting the first PCR amplification product to a second PCR amplification using a DOP-Amp primer, to obtain a second PCR amplification product; and subjecting the second PCR amplification product to an adaptor-ligation PCR, to obtain a third PCR amplification product, wherein the third PCR amplification product constitutes the nucleic acid library. | 10-02-2014 |
20140206006 | SINGLE CELL CLASSIFICATION METHOD, GENE SCREENING METHOD AND DEVICE THEREOF - Provided are a single cell classification method, a gene screening method and a device for implementing the method. In that, the single cell classification method includes the following steps: sequencing the whole genomes of a plurality of single cell samples from the same group, respectively, so as to obtain reads from each single cell sample; aligning the reads from each single cell sample to the sequence of a reference genome, respectively, and performing data filtering on said reads; on the basis of the filtered reads, determining a consistent genotype of each single cell sample, in which consistent genotypes of all the single cell samples constitute an SNP dataset of said group; aimed at said each single cell, on the basis of the SNP dataset of said group, determining a corresponding genotype for each cell at a site corresponding to a position in an SNP dataset of the reference genome; and selecting an SNP site associated with cell mutation, and on the basis of the genotype of said single cell at the site, classifying said single cell. | 07-24-2014 |
20140099642 | NONINVASIVE DETECTION OF FETAL GENETIC ABNORMALITY - The current invention is directed to methods for noninvasive detection of fetal genetic abnormalities by large-scale sequencing of nucleotides from maternal biological sample. Further provided are methods to remove GC bias from the sequencing results according to the difference in GC content of a chromosome. The current invention not only makes the detection much more accurate but also represents a comprehensive method for fetal aneuploidy detection including sex chromosome disorders such as XO, XXX, XXY, and XYY, etc. | 04-10-2014 |
