説明
Bst Plus DNA Polymerase is derived from Bacillus stearothermophilus DNA Polymerase I and has been genetically engineered to eliminate its 5’→3’ exonuclease activity while retaining robust 5’→3’ DNA polymerase activity and strong strand-displacement capability. Compared with wild-type Bst DNA Polymerase, this enzyme demonstrates significant improvements in amplification speed, yield, salt tolerance, and thermostability. Additionally, it exhibits enhanced dUTP tolerance, making it highly suitable for isothermal amplification applications such as LAMP (Loop-Mediated Isothermal Amplification). This product is glycerol-free Bst Plus DNA Polymerase, ideal for lyophilized formulation development.

b. 10× Primer Mix composition: 16 µM FIP/BIP, 2 µM F3/B3, and 4 µM each of Loop F/Loop B; primer ratios may be adjusted as needed.
2. Reaction Conditions
Incubate at 65°C for 30–60 minutes, followed by heat inactivation at 85°C for 5 minutes.
If using a UDG system, include a UDG digestion step (e.g., 25°C for 10 minutes) prior to amplification.
