Thermostable dna polymerase とは
Taqポリメラーゼ (Taq polymerase ) とは、好熱菌 Thermus aquaticus が産生するDNAポリメラーゼ（EC.2.7.7.7）である。90℃以上の高温でも比較的安定である（DNAポリメラーゼ活性は低下する）ため、PCRに利用されている。ちなみに、この酵素の名前は、産生菌の属名の頭文字と種小名の頭二文字 (Thermus aquaticus) に由来する。 Taqポリメラーゼは熱水噴出孔に生息している T. aquaticus から同定されたポリメラーゼである。このポリメラーゼはPCRのような熱 … Webb15 feb. 2024 · Taq DNA polymerase is commonly used in T-ARMS PCR genotyping. The properties of SD polymerase and Taq polymerase are different and influence the T-ARMS PCR differently (Fig. 1 a). The Taq DNA polymerase, used in the classical T-ARMS PCR, has 5′–3′ polymerase as well as 5′–3′ exonuclease activity.
