Heated Polymerase Chain Reaction (PCR)

In this dsDNA is denatured by heating the sample at its denaturing temperature and then the temperature is suddenly reduced to 55 degree C at which primer and Taq-polymerase is added, but here the difference arises i.e. specific antibodies are used to block this Taq-polymerase at annealing temperature. Now when the temperature raises for amplification to 72 degrees, the specific antibody detaches from Taq-polymerase and the amplification with greater specificity starts.[1]
