Product description

Medino® Bst Plus DNA Polymerase is derived from Bacillus stearothermophilus DNA Polymerase l. The 5 ‘-3’ exonuclease activity was removed by genetic engineering method, but the 5 ‘-3’ DNA polymerase activity and strong chain replacement activity were retained. Compared with wild-type Bst DNA Polymerase, the polymerase showed great improvement in amplification speed, yield, salt tolerance and thermal stability, and increased dUTP tolerance. It was very suitable for isothermal amplification reactions such as LAMP reaction. This product freeze-dried glycerin- free Bst Plus DNA Polymerase to solve the problem of glycerinase-free instability and could be used to make freeze-dried products.

  1. The recommended concentration of 25 mmol/L d(A/U/G/C)TP mix was 1.2 – 1.4mmol/L
  2. 10x Primers: 16 μmol/L FIP/BIP, 2 μmol/L F3/B3, 4 μmol/L Loop F/B each. The ratio of primers also could be adjusted appropriately.

2.Reaction System

The reaction was incubated at 65°C for 30 – 60 min. Heat inactivation was carried at 85°C for 5 min.

If UDG was used in the reaction system, the UDG digestion reaction should be proceeded (such as incubation at 25°C for 10 min).
