I was assuming the Ab was for Hotstart.
I don't know the life of the Ab in a tube but I thought the rapid Ab
inactivation was due to surface denaturation. Wouls the BSA coat enough to
prevent this?
The poster was using a PE9700. The 10 mins didn't refer to the Rapidcycler.

As for the variables.
Technician; Doubt it
Location; ditto
Water; Nuclease free?
Machine; almose certainly if trying to swap over a protocal.
