The fluorescent dye SYBR Green I in the master mix enables the analysis of many different targets without having to synthesize target-specific labeled probes. A balanced combination of K + and NH 4 + ions in the PCR buffer promotes specific primer annealing and enables high PCR specificity and sensitivity (see figure \"Specific primer annealing\").

As few as 10 copies of a target gene can be detected with the kit.\u003c\/p\u003e\n\n\u003cp\u003eAmplifying reference and target genes in the same reaction instead of in separate reactions increases the reliability of gene quantification by minimizing handling errors. The QuantiTect Multiplex PCR Master Mix contains a balanced combination of K + and NH 4 + ions as well as the unique synthetic Factor MP, which together promote stable and efficient annealing of primers and probes to the nucleic acid template, enabling high PCR efficiency (see table \"Components of 2x QuantiTect Multiplex PCR Kit\").
