两种荧光化学原理
●Fluorogenic 5’Nuclease Assay
–An established and proven chemistry for high specificity nucleicacid real-time quantitation
–The introduction of TaqMan®MGB (Minor Groove Binder) probes has produced a turn-key homogeneous chemistry for the detection of Single Nucleotide Polymorphisms (SNPs)
●SYBR®Green 1 Double Stranded DNA Binding Dye Assay
–Ideal for target identification (screening) assays
–A lower-cost alternative when high specificity is not required
