Monoclonal Antibodies and ELISA Test

Cards (7)

  • First Step
    Inject mouse with antigen to which antibodies are being sought
  • Second Step
    Remove the B Cells which are actively forming antibodies from Mouse’s spleen. These will be producing many antibodies
  • Third Step
    Fuse B Cells with cancer tumour cells to form hybridomas (Add detergent to break down cell membrane)
  • Fourth Step
    Separate Hybridomas too see which are producing the desired antibody. Clone them on a large scale (let them reproduce)
  • Fifth Step
    Antibodies are modified in a process called humanisation
  • Why are they called Monoclonal Antibodies?
    They are genetically identical (Clonal) and come from one B Cell (Mono)
  • Uses of Monoclonal Antibodies
    • Separation of a chemical from a mixture by binding to it
    • Immunoassay - Binding to substances so their quantity can be calculated
    • Cancer Treatment - Attach Cytoxic Drug to Monoclonal Antibody that is chosen to attach to cancer cell
    • Anti-rejection treatment after transplants - Monoclonal Antibodies can be injected that bind to specific T cells, preventing them from attacking the donar organ
