TY - CONF A1 - Kage, Daniel T1 - Fluorescence lifetime multiplex flow cytometry system (FliMFlow-MultiLife) N2 - Flow cytometry is a common tool in biological research and clinical analyses. In current developments, there are two different tendencies of interest. Firstly, we face the need for analysis methods that are capable of addressing more and more involved analysis tasks, i.e., an increasing number of fluorescent codes and markers is required. Secondly, low-cost diagnostic tests, e.g. in disease recognition, are needed in routine application. Lifetime encoding could be an attractive alternative to commonly applied color (spectral) encoding. By combining spectral and lifetime multiplexing, the number of simultaneously detectable codes might be increased by adding lifetime codes to the parameter space. Otherwise, instrumentation costs could be lowered using only lifetime encoding and thus avoiding costly excitation light sources and detectors. Here, we report on our recent progress in time-resolved flow cytometry using dye-stained lifetime-encoded polymer microparticles as a model system. We could show that the discrimination of two lifetime codes is feasible. Moreover, the simultaneous detection of a spectrally different ligand fluorescence signal excited at the same wavelength as the lifetime code fluorescence could be demonstrated.

Two different directions are currently of importance in development of new methods in this field. Whereas analyses in research become increasingly complex and require a growing number of simultaneously detectable codes and fluorescent labels, also low-cost methods and portable devices are needed in routine application. Lifetime encoding could present an alternative to common spectral multiplexing. On the one hand, it addresses the need for additional codes by combining spectral and lifetime multiplexing. On the other hand, using only lifetime encoding could help to reduce instrument costs by keeping the number of excitation sources and detectors low. Here, we report on our recent progress in employing dye-stained lifetime-encoded polymer microparticles as a model system for lifetime encoding in flow cytometry. The discrimination of two lifetime codes was achieved with two bead sets. Moreover, the simultaneous detection of a spectrally different ligand fluorescence signal could be demonstrated.
