Rotor-Gene Multiplex PCR Kit (80) The Rotor-Gene Multiplex PCR Kit is dedicated for use with the Rotor-Gene Q cycler, providing ultrafast, highly reliable quantification in multiplex, real-time PCR and two-step RT-PCR using sequence-specific probes. Up to 4 genes (e.g., 1 control gene and 3 target genes) can be quantified simultaneously in the same reaction.
