  2. Hemagglutinin (HA), an antigenic glycoprotein from Influenza viruses morphology
  3. Immunofluorescence use Antibody with fluorescent label and they
  4. C. difficile test looks for
  5. ELISA is a example of immunoassay, indirect ELISA uses
  1. a POC testing than ever before because of the Immediate results
  2. b toxin, not bug
  3. c -antigen coated to plastic well
    -protein blocks remaining plastic surface
    -Serum added(primary antibody)
    -if antibodies(bind antigen)
    -if no antibodies(antigen not bound)
    -Indicator antibody(enzyme-linked anti-Ig antibody binds primary antibody)
    -Substrate(specific for enzyme linked to secondary antibody,enzyme causes substrate to change color)
    -Reactions(color change=
    antibody in serum,no color change=
    no antibody in serum)
  4. d -trimeric protein
    -13 major antigenic classes
    -functions in viral attachment to a variety of host cells
  5. e -Bind to cell
    -Visualize under UV light

    -observe agglutination
  4. -detect specific proteins in cells
    -detect viruses in cells
    -identify microbial cells
    -identify and sort cells
    -fluorescent activated cell sorter (FACS)

    -wash unbound serum away
    -incubate with conjugated anti-Hu gamma globulin ~25 min.
    -wash unbound Ab away
    detect in fluorescent microscope

5 True/False questions

  1. In Double immunodiffusion-Antibody mixed into gel with specimens in well
    -screening for presence of antigen
    precipitate forms band around well which
    indicate presence of antigen
    -size of band relative to concentration of antigen

          

  2. Types of precipitation reactionsTest tube
    Capillary tube
    Agarose plate

          

  3. Monoclonal Antibody Production-Immunization leads to Antibody-forming cells, which fuse with tumor cells to form hybridomas.
    -Hybidomas screened for antibody production and antibody-producing hybridomas cloned
    -Monoclonal antibodies isolated for cultivation

          

  4. Direct Immunoassays areScreen for antibodies (anti-HIV, anti-rubella)

          

  5. RapidStrep is VERY specific, but noteliminate false positives
