The green dye can be placed in a sample with possible DNA and will glow a bright green if DNA is present. This is the most common use of the dye and helps qualitatively analyze if DNA is present in a substance. Although the DNA used in our samples was double stranded DNA, the SYBR Green Dye can also be used to detect single stranded DNA because it has such a high affinity. Although it was placed in the samples after being in the PCR machine, it also can be placed inside a PCR mixture and this allows the dye to bind to the single stranded DNA before it is synthesized by the Taq Polymerase. However, the result is the same. Either way it binds to DNA and glows when DNA is present. Single-Drop Fluorimeter [A description of the single-drop fluorimeter device.
