Pcr reaction parameters
Splet01. jan. 2024 · To perform high-fidelity PCR with Taq polymerase, reactions should contain a low MgCl2 concentration, not in large excess over the total concentration of dNTP substrates, and be buffered to approximately pH 6 (70 degrees C) using Bis-Tris Propane or PIPES (Table 2). Splet16. maj 2012 · PCR reactions also typically include an initial melting step at 95 °C (pre-melting) and a final extension step at 72 °C. Reagents include two sets of primers: reverse primers that hybridize to template ssDNA, and forward primers that hybridize to the complementary ssDNA.
