SEQUENCING METHOD FOR GENOMIC REARRANGEMENT DETECTION
20220364169 · 2022-11-17 ·

The present disclosure is directed to a single-end sequencing method for improved detection of genomic rearrangements such as deletions, insertions, inversions, and translocations that are present in a polynucleotide. A first priming event allows for sequencing of a target sequence, and a second priming event on an adapter allows for identification of the sequences amplified and tagged by selective amplification. The combination of priming events in the same direction facilitates read alignment and the identification of any genomic rearrangements.

Analysis of nucleic acids

Method of haplotype analysis. In an exemplary method, an aqueous phase containing nucleic acid may be partitioned into a plurality of discrete volumes. At least one allele sequence may be amplified in the volumes from each of a first polymorphic locus and a second polymorphic locus that exhibit sequence variation in the nucleic acid. At least one measure of co-amplification of allele sequences from both loci in the same volumes may be determined. A haplotype of the first and second loci may be selected based on the at least one measure of co-amplification.

11574705 · 2023-02-07 · ·

A high-throughput hybridization and reading method for biochips uses probes with different marks to specifically connect single nucleotide loci by conducting connection between the probes and target genes at different temperatures, and performing hybridization at the same temperature after the probes are connected, thereby achieving hybridization detection for various loci in a single chip. The method enables fast detection for multiple loci as required by personalized medicine. The detection is high-throughput and systematized and provides highly visualized and highly accurate results. The method allows detection for different loci at different hybridization temperatures to be done simultaneously. The method features highly uniform and repeatable detection, making biochips more efficient and utility in terms of detection. Besides, the chip is easy to prepare and use, thus having a good promotional value.
