Basics of SYBR Green Chemistry The SYBR® Green 1 Double-Stranded Binding Dye is used for the fluorescent detection of double-stranded DNA (dsDNA) generated during PCR. The SYBR Green 1 Dye binds non-specifically to dsDNA and generates an excitation-emission profile similartothatoftheFAM reporter dye. When used in combination with a passive reference, the SYBR Green 1 Dye can be employed to perform several SDS-related experiments including quantitative PCR and dissociation cure analysis. The following figure illustrates the action of the SYBR Green 1 dye during a single cycle of a PCR. 3´ 5´ When added to the reaction, the SYBR Green 1 Dye binds non-specifically to the hybridized dsDNA and fluoresces Dissociation 3´ 5´ Denaturation complete, the SYBR Green 1 Dye dissociates from the strand, resulting in decreased fluorescence Polymerization 5´ 3´ 5´ Polymerization Complete 3´ 5´ 3´ 5´ Forward Primer Reverse Primer During the extension phase, the SYBR Green 1 Dye begins binding to the PCR product Polymerization is complete and SYBR Green 1 Dye is completely bound, resultinginanetincreaseinfluorescence 5´ 3´ 5´ 3´ 5´ 3´ 5´ 5´ 3´ 5´ 3´ Theory of Operation A-3
Fluorescence Detection and Data Collection Fluorescent Sequence Detection A-4 Theory of Operation During PCR, light from an argon ion laser is sequentially directed to each well on the microplate. The light passes through the ABI PRISM Optical Adhesive Cover and the laser excites the fluorescent dyes present in each well of the consumable. The resulting fluorescence emission between 500 nm and 660 nm is collected from each well, with a complete collection of data from all wells approximately once every 7–10 seconds. A system of lenses, filters, and a dichroic mirror focus the fluorescence emission into a grating. The grating separates the light (based on wavelength) into a predictably spaced pattern across a charge-coupled device (CCD) camera. The SDS software collects the fluorescent signals from the CCD camera and applies data analysis algorithms.
