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

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.

Store this enzyme at -20°C and avoid repeated freeze-thaw cycles to preserve catalytic activity. The product is shipped Dry Ice and remains stable for up to one year from the date of manufacture when stored under recommended conditions. Aliquoting the stock solution into single-use volumes is recommended for enzymes used infrequently to minimize thermal cycling of the bulk stock.
Isothermal DNA amplification. Always verify compatibility with your specific template, buffer, and downstream workflow.
One unit (U) is defined as the amount of enzyme that catalyzes the incorporation of 10 nmol of deoxyribonucleotide into acid-insoluble material in 30 min under standard assay conditions.
This enzyme is produced as Recombinant (E. coli) and supplied as a Research Use Only (RUO) reagent. The formulation is glycerol-free, making it compatible with lyophilization, high-throughput liquid handling systems, and direct integration into IVD master mix formulations. Each lot is subjected to activity assay, purity assessment by SDS-PAGE, and functional validation prior to release. A Certificate of Analysis (CoA) and Safety Data Sheet (SDS) are available on request.
This enzyme is produced recombinantly in E. coli under stringent quality controls and validated on multiple substrate types. Key performance parameters include specific activity, substrate specificity, cofactor requirements, optimal pH/temperature range, and compatibility with downstream assays. Refer to the product datasheet for validated lot-specific activity data and recommended reaction conditions.
