Fluorescent probe bind dna
WebJan 10, 2024 · DAPI fluorescence intensity increases if attached to DNA compared to its unbound state. It is excited by UV-light with a maximum at 358 nm. Emission spectrum is broad and peaks at 461 nm. A weak fluorescence can also be detected for RNA binding. In this case, emission shifts to 500 nm. WebThe combination of probe and primers increases the precision in the amplification reaction since all three must bind to the correct target for a fluorescence signal to be generated. Probe-based assays also lets users combine multiple …
