Antibodies in diagnostics - from immunoassays to protein chips

Antibodies are used extensively as diagnostic tools in a wide array of diff erent analyses. Monoclonal and recombinant antibodies provide a never endin g source of molecules and can produce endless possibilities for novel genet ic constructs. Antibodies are still very much in vogue and are now also bei ng used in microarray analysis of the proteome using protein chips. Here, r ecent opportunities presented by antibodies as diagnostic tools are reviewe d.
