Abstract: The disclosure relates to the field of molecular virology and immunology, and discloses an anti-HPV6 L1 protein antibody and a detection method using the antibody. The antibody or its antigen-binding fragment comprises a light chain variable region or part thereof and/or a heavy chain variable region or part thereof, the light chain variable region or part thereof comprises one or more of the light chain CDR1-3 whose amino acid sequence is SEQ ID NOs: 5-7 respectively; the heavy chain variable region or part thereof comprises one or more of heavy chain CDR1-3 whose amino acid sequence is SEQ ID NOs: 8-10. The antibody has strong binding ability to HPV6L1 antigen, and has no cross-reaction with HPV11, 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58 and 59 types, and is suitable for performing immunogenicity evaluation of HPV vaccine as a detection antibody in ELISA quantification.

Abstract: Disclosed is a blood pump device. The blood pump device includes: a housing having an overflow passage, and an inlet and an outlet respectively connected to the overflow passage; a rotor assembly rotatably disposed in the overflow passage; a coil disposed in a side wall of the housing; a first permanent magnet portion disposed inside the rotor assembly; a second permanent magnet portion disposed in the side wall of the housing, the first permanent magnet portion and the second permanent magnet portion forming a radial permanent magnet bearing; a piece of electric motor magnetic steel disposed inside a rotor of the rotor assembly; and a magnetic protection portion disposed at a periphery of the coil, wherein the magnetic protection portion and the electric motor magnetic steel act together to provide an axial pre-tightening force for the rotor assembly.
