A combination of TaKaRa Ex Taq HS, a hot start PCR enzyme that uses an anti-Taq antibody, and a buffer optimized for qPCR allows high amplification efficiency and high detection sensitivity in qPCR. The 2X premixed reagent also contains Tli RNaseH, a heat-resistant RNase H, which minimizes inhibition of the qPCR reaction due to residual mRNA when using cDNA as template. This product is suitable for high-speed qPCR and allows accurate assay and detection of targets, making it possible to conduct real time PCR analyses with excellent reproducibility and reliability.
Two ROX Reference Dyes are also supplied as separate components with Cat.# RR420A, RR420B, RR420L and RR420W. These serve as convenient internal reference standards for use in normalizing signals due to non-PCR related fluorescence fluctuations that occur either between wells or over time in different instruments.
Cat.# RR420L and RR420W are larger package sizes (5 mL and 25 mL (5 x 5 mL), respectively) of SYBR Premix Ex Taq (Tli RNase H Plus). Each of these provides convenient larger packaging, and is supplied with a single, separate vial of ROX Reference Dye.
Cat.# RR42LR and RR42WR are larger package sizes (5 mL and 25 mL (5 x 5 mL), respectively), that contain ROX Reference Dye in the premix.
