Hieff™ Bst Plus DNA Polymerase



Hieff™ Bst Plus DNA Polymerase is derived from Thermophilic Geobacillus sp DNA Polymerase I, lacking 5'-3' exonuclease activity. The enzyme has stronger 5'-3' DNA polymerase activity, strand displacement activity, and dUTP tolerance, which is more suitable for anti-pollution isothermal amplification reactions, such as LAMP, CPA, etc.


  • Thermophilic DNA polymerase with strong strand displacement activity


  • Isothermal DNA amplification

  • High Sensitivity

Figure 1: Sensitivity Test

Red: 50 copies/T, response less than 15 minutes
Figure 1: The copy numbers of 50 copies/Tweres tested. 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 days
0 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 times
Blue: Repeat freeze-thaw 5 times
Green: 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.



The product should be stored at -25℃ ~ -15℃ for 2 years. Please avoid repeated freeze-thaw.
