Taq Plus DNA Polymerase, 5u/ul: Taq Plus is a mixture of Taq and Proof Reading enzyme. Taq is a thermostable DNA polymerase isolated from a strain of Thermus sp (see product number D0089). Taq Plus is used to improve the reliability and yield of conventional primer extension reaction. Taq Plus has two following advantages: High fidelity with an error frequency 1.6/10^6 ( or 0.0016/10^3) during DNA synthesis. Taq Plus increases the efficiency of polymerization reaction, resulting in a great percentage of extenuation reaction completion up to 10kb to 30kb. Taq Plus has a temperature optimum between 72-78°C and remains > 95% active following 1-hour incubation at 95°C
