IsoFast® Hot Start Bst Polymerase Colour & Mix


IsoFast® Hot Start Bst Colour consists of colorimetric quantitative isothermal amplification enzyme components combining IsoFast® Hot Start Bst Polymerase with a pH-based dye for rapid green/purple screening. IsoFast® Hot Start Bst Polymerase is a recombinant version of the large fragment of Geobacillus stearothermophilus (formerly Bacillus stearothermophilus, Bst) DNA Polymerase. This colorimetric quantitative formulation is available as a pre-assembled mix, IsoFast® Hot Start Bst Colour Mix, for direct sample and primer input. Additionally, IsoFast® Hot Start Bst Polymerase Colour is available as a separate Bst DNA Polymerase system and color buffer, allowing full customization of the assay process and maximum flexibility in setup. This isothermal amplification system enables color readout based on DNA without the need for PCR, making it highly suitable for point-of-care diagnostics and field tests. Features: - Rapid color results for green/purple tests - AptaLock™ hot start for ultra-sensitive DNA target detection - Faster polymerization rate to shorten time to results (as little as 10 minutes) - Capable of detecting down to 3 target copies per μL - Suitable for both low temperature and room temperature setup - Speeds up and increases sensitivity for early target detection - High performance over a wide temperature range from 55-70 °C

Additional Information

IsoFast® Hot Start Bst Polymerase Colour and IsoFast® Hot Start Bst Colour Mix are the latest advancements and improvements in isothermal amplification technology, designed to deliver unprecedented specificity and speed in DNA amplification processes to meet the needs of molecular diagnostics and research. Whether you are working with isothermal amplification methods such as loop-mediated isothermal amplification (LAMP) or other isothermal amplification techniques, these IsoFast® Hot Start Bst reagents ensure excellent sensitivity and reliability. Their blends leverage the power of Bst DNA polymerase hot start, which ensures minimal background amplification and maximizes target specificity. With IsoFast® Hot Start, your isothermal amplification experiments will be faster, more efficient, and easier than ever before, setting new standards for molecular biology techniques in both diagnostic applications and research efforts.

Hot start initiation is crucial in isothermal amplification techniques as it helps prevent non-specific amplification and false-positive results. Isothermal amplification methods, such as loop-mediated isothermal amplification (LAMP), rely on specific primers and enzymes to amplify a target sequence at a constant temperature, typically ranging from 60°C to 65°C. These techniques are widely used in various applications, including molecular diagnostics and pathogen detection.

Why is hot start important in isothermal color amplification?

Preventing non-specific amplification in isothermal reactions:

In isothermal amplification, it is essential to ensure that the amplification process targets only the specific sequence of interest. Non-specific amplification can occur when primers attach to unintended regions of the sample or when amplification enzymes prematurely activate the amplification process. Hot start techniques involve inhibiting the amplification reaction until the reaction reaches the desired temperature. This prevents the formation of non-specific products in the early stages of the reaction when the temperature is still below the optimal amplification temperature.

Enhancing specificity in isothermal amplification:

By preventing early amplification, hot start methods enhance the specificity of the isothermal amplification reaction. This means the reaction is less likely to amplify non-target sequences, minimizing the risk of false-positive results.

Improving sensitivity in isothermal assays:

Hot start techniques can also improve the sensitivity of isothermal amplification assays. By minimizing non-specific amplification, more reagents are available exclusively for target sequence amplification, enhancing the reaction's efficiency and detection limits.

Frequently Asked Questions

Certain types of isothermal amplification strategies lend themselves to downstream applications, e.g. RCA (rolling circle amplification) or WGA (whole genome amplification) for NGS. IsoFast® Hot Start Bst reagents can be used for this type of amplification. However, the most common type of isothermal amplification, LAMP, generates multiple species of DNA products, making it unsuitable for cloning and impractical for NGS applications.

IsoFast® Hot Start Bst Polymerase, IsoFast® Hot Start Bst Mix, IsoFast® Hot Start Bst Colour Mix, and IsoFast® Hot Start Bst Polymerase Colour are all designed to amplify DNA and cDNA targets. They are not suitable for direct amplification of RNA targets.

For amplifying RNA targets, we recommend using IsoFast® Bst 1-Step Mix for direct 1-step isothermal amplification. Alternatively, we suggest a 2-step format where RNA is first converted into cDNA using one of our UltraScript® reagents, followed by cDNA amplification with the user's preferred IsoFast® Hot Start Bst reagent.
