Abstract

In cytometry and like procedures, particles containing signal dyes are exposed to a laser, and the resulting fluorescence is assessed in two different wavelength bands. When the particle is a single-assay particle, or when the particle carries only a single dye, the fluorescences in the different wavelength bands are combined in order to assess the concentration of the signal dye.
