Can PCRBIO Hot Start Taq DNA Polymerase be used for Multiplex PCR?
Our PCRBIO Hot Start Taq DNA Polymerase is particularly suited for multiplexing due to the presence of our hot-start technology, which blocks the activity of Taq polymerase at low temperatures.
When first performing multiplex PCR, we recommend running an annealing temperature gradient from 55°C to 65°C. The annealing temperature that results in the best specificity should be used in subsequent experiments. Fast cycling conditions should not be used for multiplex PCR. We recommend a 90 second extension time to begin with and this time may be extended to increase yield.
For multiplex reactions, the reactions should be set up on ice or cooling blocs from start till finish. Primers must be designed carefully to avoid overlapping sequences as much as possible while maintaining diverse amplicon lengths that can be easily analysed with your end-detection method1-3.
