Fluorescent signal from a pcr
WebPCR products can be detected using either fluorescent dyes that bind to double-stranded DNA or fluorescently labeled sequence-specific probes. What is SYBR Green PCR? The fluorescent dye SYBR Green I binds all double-stranded DNA molecules, emitting a fluorescent signal of a defined wavelength on binding (see figure SYBR Green principle). WebCertain real-time PCR instruments require an internal reference dye for fluorescent signal normalization and correction of well-to-well optical variations. Variation in fluorescence can result from instrument design.
