With the use of DNA-binding dyes such as SYBR Green I, a melt-curve profile can be generated. The iCycler iQ system. records the total ï¬uorescence generated by SYBR Green I. binding to double-stranded DNA as temperature changes, and plots the ï¬uorescence in real time as a function of. temperature.
