The Rotor-Gene Multiplex RT-PCR Kit is designed for use with the Rotor-Gene Q and other Rotor-Gene cyclers, providing ultrafast, highly reliable quantification in multiplex, real-time one-step RT-PCR using sequence-specific probes. Depending on the cycler configuration, up to 4 RNA targets (e.g., 1 control gene and 3 target genes) can be quantified simultaneously in the same tube. Outstanding performance is achieved through the combination of a specially optimized master mix and the unique Rotor-Gene cycler. For convenience, the master mix can be stored at 2–8°C.
