Sandwich ct real-time pcr
WebbBaseline. The real-time PCR reaction baseline is the signal intensity during the first PCR cycles, typically 3 to 15 cycles, when fluorescent signal fluctuations are low. The reaction history, or “noise,” may be compared to the low-level baseline signal. For each output in real-time PCR, the baseline is determined subjectively by user ...
