SensiMix SYBR No-ROX kit contains all the components necessary to perform consistent and reproducible real-time PCR assays with your DNA template. but it does not contain an internal reference. As it is no longer essential to read the internal reference through the red channel, the red channel becomes free and can be used to monitor a probe. This reagent is suitable for those block-based and rotor-based machines where an internal reference is not required for normalisation.
