Hieff® Bst Plus DNA Polymerase is derived from Bacillus stearothermophilus DNA Polymerase I. 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. Features High amplification efficiency High dUTP tolerance The freeze-dried product form Applications Isothermal DNA amplification Specifications Polymerase Bst DNA Polymerase Heat Inactivation Incubation at 85°C for 5 min. Activity Definition 1 U refers to the amount of enzyme required to incorporate 10 nmol of dNTP into the acid-insoluble precipitate in 30 min at 65°C.

The test results showed that within 15 minutes, the results of 50 copies/T performed better, and the detection rate reached 100%. Stability Figure 2.Stability testing at the same temperature Red: 37℃ 0 day Blue: 37℃ 1 day Green: 37℃ 3 days Purple: 37℃ 5 days0 days at 37°C as a control and stability tests were carried out for 1, 3, and 5 days at the same temperature, indicating that it can still maintain a relatively stable effect at 37°C for 5 days. Figure 3. -20℃ repeated freeze-thaw stability test Red: Repeat freeze-thaw 0 timesBlue: Repeat freeze-thaw 5 timesGreen: Repeat freeze-thaw 10 times Specificity Figure 4. 48-well NTC-specific assay 48-well NTC detection was used in the specific detection of the product, and no peak was detected, indicating that the specificity was better. Storage The product should be stored at -25℃ ~ -15℃ for 1 years. Please avoid light. Documents: Manuals 14405_Manual_HB230311_EN.pdf Related Blog： What is the role of Bst DNA polymerase in LAMP?
