Unless you can develop a PCR-like assay for proteins. 
In-vitro amplification of amino-acid sequences.  Perhaps
that could win you a 'Nobel Prize.'


One could use a PCR-EIA hybrid assay to detect small quants of
tetanus toxin, that prob would work; assuming one had sometype
of mono / polyclonal anti-tetanus.
