Fluorescent antibody wavelength
WebFluorophore Selection Fluorescent probes or fluorophores (fluorescent dyes or proteins) are coupled to a secondary antibody or streptavidin to allow visualization of an analyte. Each fluorophore has its own spectral characteristics, with excitation and emission spectra particular to the molecule. WebFluorescent detection in IHC Fluorescent detection (immunofluorescence) methods use fluorochrome labels, which emit light of a longer wavelength when excited by light of a specific wavelength. Fluorescent detection is commonly used to visualize multiple antigens simultaneously.

The samples are labeled with fluorophore where they absorb the high-intensity light from the source and emit a lower energy light of longer wavelength.
WebTypically the wavelength of light needed to excite the fluorophore is larger and of greater intensity than the wavelength of emitted light. The separation of the excitation wavelength maximum and the emission wavelength maximum is referred to as Stokes shift and affects both the brightness and detection of the fluorophore.
