[London, 27th September 2023] — PCR Biosystems, a leading PCR reagent developer, has launched a new range of Bst polymerase 黄金城游戏 that offer greater sensitivity, speed, and specificity in all isothermal amplification applications. IsoFast™ Hot Start Bst Polymerase and associated ready mixes use proprietary AptaLock™ hot start technology to minimise non-specific amplification, leading to highly specific and sensitive results in as little as 30 minutes. A new colourimetric mix also enables analysts to detect results visually, vastly reducing 黄金城游戏 requirements. With these technologies, labs can now get reliable results more quickly, unlocking higher throughput testing.

Isothermal mixes are important in a range of isothermal amplification applications, including whole genome amplification, point-of-care assay development and testing, and strand displacement amplification for synthetic biology. However, a common issue with isothermal mixes is non-specific amplification — where primers bind to unintended DNA targets — because amplification often takes place at a fixed temperature which may favour non-specific primer interactions, contrary to PCR. Isothermal mixes can also lead to primer dimer formation, where primers associate with each other and are extended by the polymerase. To avoid these issues, users must design primers carefully, and evaluate many more primer pairs for a single target than they would for standard PCR— both of which can be extremely time-consuming and complex.

To help alleviate these concerns, PCR Biosystems’ newly launched IsoFast™ 黄金城游戏 use AptaLock™, a reversible hot start technology that inhibits polymerase activity below 40 °C. As such, both non-specific amplification and primer dimer formation are minimised. Once the mixture is activated on heating, results can be obtained in as little as half an hour, allowing analysts to achieve highly sensitive, specific, and rapid detection of DNA targets. High-throughput testing is also possible, as reaction plates can be set up at room temperature without any issues.

What’s more, the colour mix contains a pH-based dye that changes colour when the desired target is amplified. As a result, the mix enables labs to visually identify positive or negative results without the need for plate readers or fluorometric PCR 黄金城游戏s. The mix is therefore particularly beneficial for regions where point-of-care or field-testing laboratories lack adequate facilities and 黄金城游戏ation.

“Existing isothermal mixes present a number of challenges for organisations looking for sensitivity, specificity, and speed in DNA detection,” stated Alex Wilson, Co-founder and Business Development Manager, PCR Biosystems. “With our new mixes, labs get greatly improved specificity and sensitivity in their amplification reactions, so they obtain highly reliable results. Our internal studies show that they can be up to 50% faster than competitor mixes on tested targets too, which can make a critical difference for diagnostic and medical labs that need results quickly.”
