PCR (Polymerase Chain Reaction) is an in vitro nucleic acid amplification technology. Its basic principle is enzymatic DNA synthesis reaction, that is, in the presence of template DNA, primers and deoxyribonucleic acid, the DNA fragments are cyclically replicated and rapidly amplified by the catalysis of thermostable DNA polymerase through the steps of DNA strand thermal denaturation, primer annealing and primer extension.

TIANGEN can provide a variety of different thermostable DNA polymerases that can meet your different requirements in fidelity, amplification efficiency, amplification length and amplification specificity. They are suitable for DNA templates from various sources, amplifying DNA fragments of different lengths, and facilitating smooth downstream experiments.
