Invitrogen Lyo-ready Bst DNA Polymerase is a proprietary mutant of Bst DNA polymerase, large fragment, with a fast reaction speed, increased sensitivity, and increased tolerance to inhibitors. By retaining strong strand-displacement activity, this enzyme helps enable highly efficient isothermal amplifications such as loop-mediated isothermal amplification (LAMP).

Invitrogen Lyo-ready Bst DNA Polymerase is a proprietary mutant of Bst DNA polymerase, large fragment, with a fast reaction speed, increased sensitivity, and increased tolerance to inhibitors. By retaining strong strand-displacement activity, this enzyme helps enable highly efficient isothermal amplifications such as loop-mediated isothermal amplification (LAMP).

Lyo-ready Bst DNA Polymerase possesses 5´→3´ DNA polymerase activity and lacks 5´→3´ exonuclease activity and 3´→5´ exonuclease activity. It is also a glycerol-free enzyme, enabling assay lyophilization and use in microfluidics-based technologies.

Lyo-ready Bst DNA Polymerase features
• Fast target detection in as little as 10 minutes
• Enhanced sensitivity down to 50 copies using optimized reaction buffer in (RT-)LAMP reaction
• Robust amplification, even from inhibitor-containing RNA or DNA samples
• Ability to optimize LAMP or RT-LAMP reactions to fit your needs

Applications
Lyo-ready Bst DNA Polymerase can be used for a wide variety of applications including:
• Loop-mediated isothermal amplification (LAMP)
• Whole genome amplification (WGA)
• Rolling circle amplification (RCA)
• Recombinase polymerase amplification (RPA)
• Helicase-dependent amplification (HDA)
• Exponential amplification reaction (EXPAR)

Notes
1. If performing real-time LAMP detection with SYTO 9 Green Fluorescent Nucleic Acid Stain, dilute the stock to 50 μM with nuclease-free water before every use.
2. SuperScript IV Reverse Transcriptase and RNaseOUT Recombinant Ribonuclease Inhibitor are recommended for reactions containing RNA targets.

常见问题解答 (FAQ)

How is 1 unit of enzyme activity defined for Lyo-ready Bst DNA Polymerase?

One unit of enzyme activity is defined as the amount of enzyme that will incorporate 10 nmol of dNTP into a polynucleotide fraction at 65 degrees C in 30 min.

Does Lyo-ready Bst DNA Polymerase incorporate dUTP?

Lyo-ready Bst DNA Polymerase has the ability to incorporate dUTP during amplicon generation. Use of 100% of dUTP instead of dTTP in the dNTP mix can lead to slower target detection.

I noticed that my Lyo-ready Bst DNA Polymerase is frozen after storage at -20 degrees C. Is it still good to use?

Lyo-ready Bst DNA Polymerase comes in a storage buffer that does not contain glycerol. Product freezing doesn't affect its performance or stability. We do not recommend freeze-thawing Lyo-ready Bst DNA Polymerase for more than 20 cycles. Lyo-ready Bst DNA Polymerase is stable for 24 months when stored at -20 degrees C.

Do you offer Lyo-ready Bst DNA Polymerase in lyophilized/dry format?

No. However, Lyo-ready Bst DNA Polymerase comes in a glycerol-free formulation that can be directly air-dried or lyophilized. Dry formulation maintains stability and shows good performance after reconstitution in 10X Bst Reaction Buffer.

How can I eliminate non-specific amplification for LAMP reaction using Lyo-ready Bst DNA Polymerase?

LAMP method is fast and robust, but can often result in non-specific amplification, leading to false positive results. To help ensure reliable results and control non-specific amplification:
- Make sure that the work environment and reagents are clean. We recommend cleaning the workspace regularly to prevent contamination.
- Set up the reactions on ice to avoid non-specific amplification products.
- To enhance specificity in LAMP, primer design and optimization is required. We recommend following the primer design guidelines in the user guide (https://assets.thermofisher.com/TFS-Assets/LSG/manuals/MAN0029128-lyo-ready-Bst-DNA-polymerase_UG.pdf). Ensure that the primer melting temperature is neither too high nor too low. Low temperature may result in non-specific primer binding, and high temperature may inhibit primer binding to the template.
- Other reaction parameters such as reaction time or Bst DNA Polymerase concentration can also be optimized. Depending on the primer design and template concentration, Bst DNA polymerase amount per reaction can be decreased down to 1 U. If end-point detection is used, time can be an important factor for non-specific amplification. Reducing the incubation time by several minutes may help distinguish the NTC from the sample.
