Publication number: 20200032330Abstract: Methods, compositions and kits are provided to amplify the amount of genomic methylated DNA can by subsequently analyzed and/or sequenced. It has particular use with small amounts of DNA, including, but not limited to cell free DNA samples. In some embodiments, the ratio of polymerase and methyltransferase is controlled in order to provide maximum yields. In some embodiments, a dual primase/polymerase is used.Type: ApplicationFiled: March 8, 2018Publication date: January 30, 2020Inventors: Chuan HE, Boxuan Simen ZHAO, Pradnya NARKHEDE, Chang LIU, Xiaolong CUI

Publication number: 20200032332Abstract: Provided is a second generation sequencing-based method for simultaneously detecting microsatellite locus stability and genomic changes (prettyMSI), especially an application of the detection method in assisting in the diagnosis of patients with colorectal cancer and a corresponding kit. Microsatellite loci are selected from the 22 microsatellite loci as shown in table 1, or any combination of 15, 16, 17, 18, 19, 20, and 21 microsatellite loci of the 22 microsatellite loci.Type: ApplicationFiled: January 25, 2018Publication date: January 30, 2020Inventors: Zhihong ZHANG, Yusheng HAN, Shaokun CHUAI, Chenglin LIU, Zhou ZHANG, Wanglong DENG, Bingsi LI, Fang LUO, Jing LIU, Han HAN-ZHANG

Publication number: 20200032333Abstract: A method of forming a plurality of lipid bilayers over an array of cells in a nanopore based sequencing chip is disclosed. Each of the cells comprises a well. A salt buffer solution is flowed over the array of cells in the nanopore based sequencing chip to substantially fill the wells in the cells with the salt buffer solution. A lipid and solvent mixture is flowed over the array of cells to deposit the lipid and solvent mixture over at least some of the wells in the cells. A first portion of the cells, each having a lipid bilayer over its well, is detected. A second portion of the cells, each having a lipid membrane but not a lipid bilayer over its well, is detected. An electrical lipid-thinning stimulus is selectively applied to the second portion of the cells but not to the first portion of the cells.Type: ApplicationFiled: September 20, 2019Publication date: January 30, 2020Inventors: Kevin Aliado, Roger J.A.
