Yes, it uses an antibody-mediated, hot-start polymerase. During the initial denaturation step of qPCR cycling, polymerase activity is unblocked when the polymerase is released from the antibody. This hot-start enhances specificity and sensitivity of the qPCR by avoiding non-specific amplification of DNA and primer dimer formation. It is therefore critical to follow the cycling conditions provided in the PrimeTime Gene Expression Master Mix protocol.
