AcuGenix™ Bst Hot Start DNA Polymerase-V3
AcuGenix™ Bst Hot Start DNA Polymerase-V3, E105, is supplied for DNA strand displacement reaction.



Product overview
Bst DNA polymerase is derived from Bacillus stearothermophilus DNA Polymerase I. Bst DNA polymerase retains the activity of 5'→3' DNA polymerase by genetic engineering technology, removes the activity of 5'→3' exonuclease, and has the ability of strand displacement.
Available versions
Features and applications
- For LAMP; Aptamer-modified hot-start isothermal amplification enzyme; no separate activation step required.
- High inhibitor resistance, robust impurity tolerance, and superior sample compatibility.
- Enables room-temperature assembly of a contamination-proof system, effectively preventing amplicon aerosol contamination.
- DNA strand displacement reaction.
- LAMP isothermal amplification.

Conclusion 1: After accelerated aging at 37°C for 7 days and at 37°C for 14 days, E105 showed stable amplification at 0.1 pg/μl and 0.01 pg/μl, with ΔCt < 2 min compared with the -20°C control.
4. Enzyme Activity Assay

Conclusion 1: E105 effectively remained inactive at 30°C and was fully activated at 65°C.
