Spectral Flow Cytometry

Conventional flow cytometry uses mirrors and filters to select specific wavelength ranges for detection of signal from different fluorophores on individual PMTs.

Spectral flow cytometry uses dispersive optics, such as prisms or gratings, to disperse the collected light across a detector array, allowing the full spectra from each particle to be measured. Spectral unmixing or other analyses can then be performed on the spectral data to determine the amount of individual fluorophore contributing to the mixture spectra or extract other information from the spectra. Spectral flow cytometry represents a new approach to instrument design, and enables new classes of applications not possible with conventional flow cytometry.
