Why is the QuantiFast denaturation step different for PCR and RT-PCR runs in the two-step protocol for the ABI 7500 and other cyclers?

This is due to differences in composition between PCR and RT-PCR buffers. QuantiFast PCR Buffers are optimized for fast amplification with shortest possible PCR steps, while QuantiFast RT-PCR Buffers ... more.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
