  • Method of Preparing Magnetic Bead Type Nasopharyngeal Enzyme Immunoassay Reagents by Polymerase Chain Reaction
    Publication number: 20130337434
    Abstract: A method of preparing magnetic bead type nasopharyngeal enzyme immunoassay reagents by polymerase chain reaction according to this invention offers in-vitro diagnostic reagents by means of utilizing nanotechnology. This method uses magnetic beads to coat EBV nuclear antigen (Epstein-Barr virus nuclear antigen, EBNA1) or early antigen (Early Antigen, EA). The use of polymerase chain reaction (polymerase Chain Reaction PCR) is for amplified detection. It is found that positive controls of different concentrations, after amplified by PCR, change in their brightness and concentration. That reveals the EBV antigens on the magnetic beads can specifically detect IgA antigens in the serum.
