在染色双链 DNA 时, BRYT Green® 荧光染料比 SYBR® Green I 产生更明亮的荧光。与 SYBR® Green I 相比,该染料对 PCR 的抑制作用更小,使扩增更有效,在采用与 SYBR® Green I 相同的波长检测条件和设置的情况下,通常能更早得到 Ct 值,线性范围也更宽。 CXR 参比染料的检测波长和设置与 ROX™ 相同。 GoTaq® qPCR Master Mix 可用于任何一种能检测 SYBR® Green I 或 FAM™ 染料的实时热循环仪。 GoTaq® qPCR Master Mix 含有低浓度的 CXR 参比染料。如果您的热循环仪要求使用的参比染料浓度较高,请向反应体系中加入 100X 的 CXR 参比染料,使其终浓度为 1X 。

原厂资料:
Performing precise, accurate RT-qPCR analysis can be difficult when the target copy number is low or when PCR inhibitors are present. The GoTaq® 2-Step RT-qPCR System is a reagent system for quantitative analysis of RNA using a 2-step RT-qPCR protocol. The BRYT Green® Fluorescent Dye and optimized buffer formulations allow robust, reliable cDNA synthesis of a full range of rare and abundant transcripts, even in the presence of inhibitors, using the GoScript™ Reverse Transcription System and quantification using the GoTaq® qPCR Master Mix. The system is compatible with all real-time PCR instruments in both fast and standard cycling conditions.
Features - Benefits
Brighter Signal: Sensitive detection for earlier quantitation of low- and high-copy-number targets.
Enhanced Stability: Room temperature setups, suitable for automation and high-throughput detection.
Versatility: Compatible with both fast and standard qPCR cycling methods.
Robustness: High-efficiency, full-length cDNA synthesis in the presence of inhibitors.
