  • Patent number: 12352760
    Abstract: A protein scaffold capable of carrying radioactive signals and application thereof in antibody detection are provided. The present disclosure successfully finds out a protein scaffold R12 capable of carrying radioactive signals, which is used for assisting part of antigens to capture corresponding antibodies; and because the method is used for carrying signals and eliminating more severe screening conditions of cross reaction in the screening process, the method is not limited to the method in application, and the method can be directly used for a technical platform which only needs to eliminate the cross reaction.

  • Patent number: 11703502
    Abstract: A glycemic management related analyte detecting assay device (10) and method are provided for detecting and quantifying analyte concentrations in a fluid sample. The assay device includes an absorbent body containing an assay forming a detection zone for receiving a fluid test sample. The absorbent body is provided in a chamber of the device. The assay can detect one or more of a glycemic analyte selected from the group consisting of fasting plasma blood glucose, oral glucose, % glycated hemoglobin, and fasting insulin concentrations. In one embodiment, a container includes an absorbent body having a plurality of superimposed membranes (30, 32, 34, 36) where each membrane contains a reactant and a color indicator for detecting the presence of a selected analyte above a predetermined concentration in the fluid sample. The absorbent body and/or the assay include a color indicator that is able to provide a visual indication of the presence of one or more glycemic analytes present in the test sample.

  • Patent number: 11693008
    Abstract: Match-paired monoclonal antibodies against major royal jelly protein 4 (MRJP4) are secreted by hybridoma cell lines having microbial deposit numbers of CGMCC No. 17294 and CGMCC No. 17295, which are used in an ELISA kit and a colloidal gold immunoassay strip for detecting the MRJP4. The positive and MRJP4-specific cell lines are obtained by cell fusion using an antigen of MRJP4 recombinant protein and a cross-reaction with other major royal jelly proteins. The MRJP4 recombinant protein is used as an antigen to obtain several positive cell lines by cell fusion and two MRJP4-specific fusion cell lines are obtained by a cross-reaction with other major royal jelly proteins. Primary screening of a matched antibody pair is performed according to antibody pairing for recognizing different epitopes.
