Hi,
    A pathologist asked me today if I could locate some references for CSA
(catalyzed signal amplification). If anyone can point me in the right
direction I'd appreciate it. (BTW Pubmed was not very helpful).
    I'd also like to point out some of the difficulties with the system. I
have only done it once, so I couldn't say exactly what the inherent pitfalls
might be. He should know the good with the bad.
Thanks
