Dear Chun-Nan,
The CleanAmp™ dNTPs have a half life of 5 minutes at 95°C in PCR buffer. At 92°C the deprotection rate will be slightly slower however this temperature should allow deprotection of enough of the CleanAmp™ dNTPs to work in your PCR. If needed, you could extend the time of the initial denaturation. Please contact us if you have any additional questions.
Best Regards,
Sabrina
