Antigen microarrays, protein chips

  • Protein arrays are ordered arrangements of several (upto thousands) of proteins,
    allowing the measurement of such high numbers of molecular interactions
  • Interactions between antigens and antibodies can also be monitored on microarrays
  • Identification of the targets of circulating antibodies out of a library of antigens
    generates an immunologic fingerprint: the antibody profile
