- Quantitation
The Quantitative PCR instrument consists of a thermal cycler housed together with a digital fluorometer detector. The principle behind the method is that as the PCR amplification process progresses, there is an increase in fluorescence from SYBR® Green dye. As the SYBR® Green dye binds to double-stranded amplicons, it undergoes a conformational change and emits fluorescence at a greater intensity.07 For forensic DNA analysis the most common SYBR® Green method is Alu-based, which targets human specific Alu sequences.08
