  • What Is Bst Polymerase?

    A strand-displacing DNA polymerase that powers rapid isothermal amplification workflows, Bst polymerase is the core enzyme behind LAMP and many next-generation molecular detection technologies

    Section image

    Bst polymerase is a strand-displacing DNA polymerase originally derived from Bacillus stearothermophilus. Unlike conventional DNA polymerases that require thermal cycling for strand separation, Bst polymerase can synthesize new DNA while simultaneously displacing existing strands, enabling efficient amplification under constant-temperature conditions.

    This unique strand displacement activity makes Bst polymerase the essential enzyme for Loop-Mediated Isothermal Amplification (LAMP), one of the most widely adopted isothermal amplification technologies. By eliminating the need for thermal cycling, Bst-based amplification enables rapid, simple, and highly efficient nucleic acid detection.

    Over the past decades, Bst polymerases have evolved beyond the original enzyme through protein engineering and formulation optimization. Modern Bst variants offer improved specificity, higher activity, HotStart control, RNA amplification capability, and enhanced compatibility with advanced molecular diagnostic workflows.

  • The Evolution of Bst Polymerase Technology

    Through continuous enzyme engineering and formulation innovation, SBS Genetech has developed advanced Bst polymerases with enhanced performance and flexibility for next-generation isothermal amplification.

    The evolution of LAMP has been driven by advances in Bst polymerase engineering. While early Bst polymerases enabled efficient strand displacement amplification, modern applications require higher specificity, improved reaction control, and enhanced stability.

    SBS Genetech’s HotStart Bst reagent series integrates advanced enzyme engineering with optimized formulations to improve assay reliability. HotStart technology helps minimize non-specific amplification and reduce false-positive results, while the lyophilized formulation enables stable and convenient molecular diagnostic workflows.

  • Why Choose SBS Genetech HotStart Bst Polymerase?

    The HotStart Bst reagent series, carefully developed by SBS Genetech, is a high-performance solution for LAMP amplification, compatible with both DNA and RNA target detection. Built on rapid and highly tolerant enzymatic performance, it provides robust, fast, and ultra-sensitive amplification. The integration of HotStart technology effectively reduces false positives by preventing premature activity at lower temperatures.
    Its proprietary lyophilized formulation grants this reagent exceptional versatility—fulfilling standard research needs while enabling seamless development and manufacturing of lyophilized products using a single formulation.

    Thermostable Aptamer for HotStart Control

    The entire LyoMix and lyophilized microbead series incorporates a HotStart aptamer that ensures >90% inhibition of enzyme activity below 30 °C and complete activation within 1 minute above 60 °C. This enables convenient room-temperature setup and substantially reduces nonspecific amplification under low-temperature conditions.

    2

    Elevated Reaction Temperature Enhances Specificity

    The Bst P DNA/RNA Polymerase series supports amplification at 70 °C, which significantly reduces primer-dimer formation, improves amplification specificity, and facilitates more efficient nucleic acid release from crude samples.

    3

    Helicase-Enabled pLAMP Simplifies Primer Design

    Integrated helicase allows for pLAMP (prime LAMP) amplification without the need for F3/B3 outer primers. It also permits halving the amount of FIP/BIP primers used, further reducing nonspecific amplification and greatly improving amplification uniformity.

    4

    Ready-to-Lyophilize Formulation for Versatile Application

    Supplied as a pre-lyomix liquid formulation, the reagent offers exceptional versatility—supporting routine research use and enabling streamlined development and large-scale production of lyophilized products within a single formulation system.

  • HotStart Bst DNA/RNA v.s. HotStart Bst P DNA/RNA

    Both Bst DNA/RNA Polymerase and Bst P DNA/RNA Polymerase demonstrate rapid amplification capabilities; however, in most cases, Bst P DNA/RNA Polymerase delivers noticeably faster amplification under identical primer conditions. Thanks to its elevated reaction temperature (70 °C), it also offers higher specificity, improved sensitivity, and reduced primer consumption. Therefore, for new projects, it is recommended to begin with the Bst P DNA/RNA Polymerase system for testing and optimization. If the desired detection performance is not achieved, the Bst4.0 system can be used as an alternative.

    Interestingly, some primer sets perform particularly well at 65 °C for reasons that are not yet fully understood—this preference does not appear to correlate with primer Tm or GC content. Currently, as LAMP amplification at 70 °C is a proprietary technology unique to SBS Genetech, most commercial LAMP reagents from other suppliers operate within the 60–65 °C range. As such, primer sets screened under these conditions can be seamlessly adapted to the Bst DNA/RNA LyoMix system.
