Grin...not so seriously,
Since PCR or the idea of PCR relies heavily on massive
amplification of the target sequence , you would have to come up with
a method to do the same with proteins, in order to make detection
easier. The good thing about DNA or RNA is that with the use of a
polymerase or transcriptase you can make a copy of the target
sequence...the bad thing about proteins (grin as far as I know) is
that there is no natural system for duplicating a protein without
going through translation.
