Fluorescein fluorescent stability over time
Did you know?
WebIn real-time PCR, fluorescent DNA primers and probes offer two main advantages over DNA-binding dyes. First, these molecules specifically detect the target sequence, so nonspecific products are not detected and do not affect the accuracy of quantification. WebFluorescent molecules, also called fluorophores or simply fluors, respond distinctly to light compared to other molecules. As shown below, a photon of excitation light is absorbed by an electron of a fluorescent particle, which raises the energy level of …
