NZYSupreme One-step RT-qPCR Probe Master Mix, ROX plus is an optimized and highly efficient reaction mixture developed for first-strand cDNA synthesis and subsequent real-time PCR in a single tube. This offers great convenience and minimizes the risk of errors and contaminations. The master mix, formulated as a 2× reaction mixture, contains all components necessary for both cDNA synthesis and real-time PCR (including enzymes, dNTPs, stabilizers and enhancers), except primers, probes and RNA template. This master mix was engineered with a dual hot-start enzyme control mechanism to provide the highest detection sensitivity. In addition, the latest developments in PCR enhancers have been incorporated in the NZYSupreme One-step RT-qPCR Probe Master Mix, including buffer chemistry and incorporation of highly robust engineered enzymes.
