Fluorescent signal from a pcr
WebFluorescent signals can be amplified using 1) avidin–biotin or antibody–hapten secondary detection techniques, 2) enzyme-labeled secondary detection reagents in conjunction with fluorogenic substrates … 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).
