Interesting question. Both produce hot probes that work well but PCR may
have some advantages. E.g., PCR should produce far more labeled material and
would be less expensive to make. The cost aspect may not be true because
I'm thinking of random priming kits (around $5/reaction) vs components for
PCR (around $1/reaction), not including labeled nucleotide. Anybody have
real numbers?
