FAQ
Frequently Asked Questions
They are often used interchangeably in practice. Strictly, a fluorophore is the part of a molecule responsible for fluorescence, while a fluorochrome often implies the entire functional dye molecule used as a biological stain.
Fluorescence microscopy (including confocal), flow cytometry, immunohistochemistry, fluorescent in situ hybridization (FISH), and various immunoassay platforms.
Yes, examples include FITC (green), TRITC (red), Cy5 (far-red), DAPI (blue, binds to DNA), and Phycoerythrin (very bright orange).
The choice depends on the light source (excitation wavelength) and detectors available on the microscope, the need to avoid spectral overlap when using multiple labels, and the brightness (quantum yield) required for detection.
