Real Time PCR Dyes

Dye Structure Color Vendor Cat # Price Features
SYBR Green 1 Green unstable at 4 °C
SYTO-82 Orange does not inhibit PCR, show no preferential binding to GC rich sequences and does not influence melting temperature, Tm, even at high concentrations
SYTO-13 Green does not inhibit PCR, show no preferential binding to GC rich sequences and does not influence melting temperature, Tm, even at high concentrations
SYTO-9 Green produces highly reproducible DNA melting curves over a broader range of dye concentrations, low PCR inhibition
SYTO-16 melting curve analysis: produces the sharpest peaks.
SYTO-80 Orange
EvaGreen Green melting curve analysis: produces the sharpest peaks.
