ABSTRACT

A typical thermal cycling protocol is given in Table 4.2. After an initial denaturation step at 95°C, steps 2, 3, and 4 are then sequentially performed for 35 cycles, followed by step 5 at 72°C to ensure that the final round of strand synthesis at high substrate concentration is completed. The 6th step, involving reduction of the temperature to 4°C, is used to terminate all reactions for convenient holding until agarose gel electrophoresis is performed. The time required to traverse from one temperature to another is referred to as the
