TaqMan® probe signal production Whether an MGB or non-MGB probe is chosen, both follow the same pattern for signal production. In the early PCR cycles, only the low, quenched reporter signal is detected. This early signal, automatically subtracted to zero in the real-time PCR software, is termed “baseline”. If the sample contains a target, eventually […]

Real-time PCR fluorescence detection systems Real-time fluorescent PCR chemistries Many real-time fluorescent PCR chemistries exist, but the most widely used are 5” nuclease assays such as TaqMan®Assays and SYBR® Green dye–based assays (Figure 1). The 5” nuclease assay is named for the 5” nuclease activityassociated with Taq DNA polymerase (Figure 2). The 5” nuclease domain
