Abstract: The present invention provides a rabies virus monoclonal antibody 2F2 and universal rabies virus antibody rapid detection test paper and belongs to the technical field of biological detection. An amino acid sequence of the monoclonal antibody 2F2 is shown as SEQ ID No. 1. The monoclonal antibody 2F2 provided by the present invention specifically binds to rabies virus G proteins, and preparation of the monoclonal antibody 2F2 into test paper has the advantages of rapidity, accuracy, sensitivity, specificity and low cost.

Abstract: The present disclosure disclosed recombinase aided amplification (RAA) primers and kits for the detection of hepatitis c virus. Nucleotide sequences of the RAA primers include: an upstream primer: 5?-FITC-CTTGGGATATGATGATGAACTGGTCACCTAC-3? (SEQ ID NO. 1); and a downstream primer: 5?-Biotin-AAGAGTAGCATCACAATCAGAACCTTAGCC-3? (SEQ ID NO. 2). The HCV detection by using the RAA primers screened by the present disclosure has good specificity and high sensitivity (at least 10 copies/?L can be detected). The RAA primers can be used to prepare an HCV detection kit and construct an RAA amplification system. And combined with a lateral flow chromatography technology, the present disclosure can achieve rapid and low-cost detection of HCV and visual result judgment, no complex professional background is required, the use process is convenient and fast, and the detection results are safe and reliable.

Abstract: Provided is an application of an artificially expressed HSP27 protein in detecting ?2-adrenergic receptor stimulant drug residue.

Abstract: Provided is a nucleic acid aptamer screening method based on the localized surface plasmon resonance technology, falling within the fields of molecular recognition and nucleic acid aptamer screening. The method screens out a nucleic acid aptamer that can specifically bind to a target mainly with the aid of a localized surface plasmon resonance personal molecular interaction analyzer. The screening method comprises: taking a nano-gold chip as a medium, fixing the target on the medium, and then carrying out the visualized screening of the nucleic acid aptamer by taking the nucleic acid aptamer as a recognition element. With the aid of the LSPR-SELEX technique, the method does not require any marker during the process of detection by using a solid chip, and maintains the spatial structure and biological activity of the nucleic acid aptamer at the maximum.
