  • Publication number: 20250092454
    Abstract: The present application relates to the technical field of information and relates to a sequencing method. The sequencing method provided by the present application includes the following steps: using a sequencing system to perform base extension reactions on nucleic acid samples; and outputting sequencing data to an external server at nodes according to preset numbers of base extension cycles, and outputting base calling results by the external server on the basis of the sequencing data. The sequencing method provided by the present application enables the transmission of sequencing intermediate files of the preset numbers of base extension cycles and, by means of the base calling data for the sequenced samples according to preset requirements, helping increase the efficiency of sequencing of nucleic acid samples.

  • Publication number: 20230393159
    Abstract: The present invention relates to the field of detection of dimethyltryptamine. In order to solve the problems in the prior art that liquid chromatography-tandem mass spectrometry for detection of dimethyltryptamine has high requirements for instruments and operators and is difficult to popularize and low in detection speed, the present invention discloses a dimethyltryptamine hapten, an artificial antigen and preparation methods and application thereof. The dimethyltryptamine hapten is obtained by a reaction of N,N-dimethyl-5-hydroxytryptamine as a precursor and glutaric anhydride. The artificial dimethyltryptamine antigen obtained from the dimethyltryptamine hapten can be used for preparing a dimethyltryptamine monoclonal antibody and a dimethyltryptamine colloidal gold-fluorescence test paper.

  • Patent number: 11493452
    Abstract: A rotating seal-type liquid testing apparatus includes a lower cup component, an upper cup body, a top cover and a testing element. The lower cup component includes a lower cup body, a high liquid baffle, a low liquid baffle and a water-absorbing sealing plug. The low liquid baffle and the high liquid baffle divide a bottom of an inner cavity of the lower cup body into a reaction region and a cut-off region. An edge of a bottom surface of the inner cavity of the lower cup body is provided with a vent hole, and the vent hole is positioned in the cut-off region. The upper cup body is disposed in the lower cup body, a bottom surface of an inner cavity of the upper cup body is provided with a liquid outlet, and the liquid outlet is connected to the reaction region in the lower cup body.
