Publication number: 20240212790Abstract: Methods and systems for single molecule sequencing using concatemers of copies of sense and antisense strands. Concatemers are provided, for example, by carrying out rolling circle amplification on a circular molecule having sense and antisense regions to produce repeated copies of the sense and antisense regions connected by linking regions. The circular molecules can be produced by ligating hairpin adapters to each end of a double-stranded nucleic acid having a sense and antisense strand. The ligations can be carried out, for example using blunt end ligation. In some cases, a single molecule consensus sequence for a single template molecule is obtained. A single read from each template molecule can be obtained by comparing the sequence information of the sense and antisense regions.Type: ApplicationFiled: June 27, 2023Publication date: June 27, 2024Inventors: Kevin Travers, Geoff Otto, Stephen Turner, Cheryl Heiner, Congcong Ma

Publication number: 20230392198Abstract: Method and system for detecting reverse transcriptase activity of a sample by digital assay. In an exemplary method, a reaction mixture including the sample, an RNA polymer, and reagents for reverse transcription may be prepared. Complementary DNA (cDNA) may be synthesized in the reaction mixture using the RNA polymer as a template. An amount of the cDNA synthesized may be proportional to the reverse transcriptase activity of the sample. Partitions may be formed after synthesizing the cDNA. The partitions may contain copies of the cDNA at partial occupancy. Each partition may include a portion of the reaction mixture. A target representing the cDNA may be amplified in the partitions. Amplification data for the target may be collected from the partitions.Type: ApplicationFiled: May 26, 2023Publication date: December 7, 2023Applicant: Bio-Rad Laboratories, Inc.Inventors: Congcong MA, Duc DO, Douglas GREINER
