双重热启动机制的出色特异性 特异性是获取 SYBR™ Green 反应的高质量数据的关键,在严格的引物结合前,可以通过在较低温度下控制 Taq DNA 聚合酶来增强特异性。PowerUp™ SYBR™ Green 混合液采用 Dual-Lock™ Taq DNA 聚合酶,其结合了两种独特的热启动机制,有助于控制其活性,并防止聚合酶在低温下出现不需要的早期活性。在评估24种不同引物组的实验中,PowerUp™ SYBR™ Green 预混液生成单熔解曲线100%的时间与高特异性扩增一致
CT 在较宽的动态范围内具有严格的重现性 PowerUp™ SYBR™ Green 预混液在广泛动态范围内对各种受测靶标表现出了出色的重现性(如图所示)。此外,此预混液还可在6个对数级上样量下实现高效扩增。与其他竞品混合液不同,在动态范围实验中,PowerUp™ SYBR™ Green 预混液未在高 cDNA 上样量、低相关系数下出现抑制现象,并在全动态范围内维持了稳定的效率,极大限度确保了数据质量的可信度(如图所示)。
2x 混合物包含 SYBR Green 染料、双重锁定 Taq DNA 聚合酶、含有 dUTP/dTTP 混合物的 dNTP、热不稳定 UDG、ROX 被动参比染料和优化的缓冲液组分。包含10 X 1 mL 管,足以进行1000次 20-μL 反应(每个反应 10 μL 预混液)。
储存于 2–8°C。
常见问题解答 (FAQ)
Which enzyme does the PowerUp SYBR Green Master Mix (Cat. No. A25741, A25742, A25743, A25776, A25777, A25778, A25779, A25780, A25918) have? What is the advantage of this enzyme?
The PowerUp SYBR Green Master Mix uses a Dual Lock Taq DNA Polymerase enzyme. This enzyme combines two unique hot-start mechanisms to help control its activity and to prevent undesirable early activity of the polymerase at low temperatures. As such, this mechanism provides excellent specificity.
Can I store PowerUp SYBR Green Master Mix for qPCR at -20 degrees C?
We have not tested PowerUp SYBR Green Master Mix for qPCR at -20 degrees C. We have only performed accelerated and real-time stability testing at 2-8 degrees C, as this is the recommended and most convenient storage temperature.
What is the recommended storage temperature for the PowerUp SYBR Green Master Mix?
The recommended storage temperature for the PowerUp SYBR Green Master Mix is 2-8 degrees C.
What is the difference between Power SYBR Green Master Mix and PowerUp SYBR Green Master Mix?
Both master mixes are compatible with all Applied Biosystems Real Time PCR instruments, but Power SYBR Green Master Mix can only be run in Standard Mode. PowerUp SYBR Green Master Mix contains a heat-labile UDG, which allows for review of PCR products up to 72 hrs post-PCR (unlike Power SYBR Green Master Mix). Finally, PowerUp SYBR Green Master Mix uses Dual-Lock Taq DNA Polymerase, which uses a combination of two hot start modifications for exceptional specificity.
Which instruments are compatible with the PowerUp SYBR Green Master Mix?
PowerUp SYBR Green Master Mix can be used in either standard or fast cycling mode and is compatible with all Applied Biosystems Real-time PCR instruments (except the 7900HT Fast mode instrument). It is also compatible with the Bio-Rad iQ5, Roche LightCycler 480, and Agilent MX3005P systems.
