WebNov 4, 2024 · A fluorophore is attached to the 5’ end of the probe and a quencher to the 3’ end. If no amplicon complementary to the probe is present, the probe remains intact and low fluores- cence is detected. If the PCR results in a complementary target, the probe binds to it during each annealing step of the PCR.

WebFluorophores (or fluorochromes) are commonly used in conjugation with antibodies as detection reagents in applications such as flow cytometry. Fluorophores can absorb and emit light within a range of wavelengths, normally referred to as the absorbance (excitation) and emission spectra. WebA fluorophore is excited most efficiently by light of a particular wavelength. This wavelength is the excitation maximum for the fluorophore. Light with a wavelength near the excitation maximum can also cause excitation, as shown by the shaded areas below, but it does so less efficiently. Excitation range and maximum.
