  • Publication number: 20240264128
    Abstract: The present disclosure provides a method for increasing a number of proteins and/or peptides identified, including: S1. adding a binding buffer and an aluminosilicate zeolite to a sample to be tested to obtain a first suspension; S2. incubating the first suspension, subjecting an incubated first suspension to first high-speed centrifugation to obtain a first supernatant and a first precipitate, discarding the first supernatant, and retaining the first precipitate; S3. repeating a process as follows several times: resuspending the first precipitate with a washing buffer to obtain a second suspension, subjecting the second suspension to second high-speed centrifugation to obtain a second supernatant and a second precipitate, discarding the second supernatant, and retaining the second precipitate; and S4. preparing the second precipitate into a protein sample, and subjecting the protein sample to mass spectrometry detection.

  • Publication number: 20240212790
    Abstract: 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.

  • Publication number: 20230392198
    Abstract: 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.
