Fluorescent Particles (Up To 5 Micron)

Fluorescent particles with single or multiple fluorophores are available in various sizes, emission spectra and combinations. Many are suitable for uses in flow cytometry, fluorescence microscopy, phagocytosis studies and cell labeling. Please contact us for fluorescent particle recommendations.

The SPHERO™ Fluorescent Microparticles are prepared by either staining the polystyrene core of the particles with a solution of appropriate fluorophore or by polymerizing a fluorophore in styrene in the presence of polystyrene core particles. As a result, a wide variety of fluorescent particles can be prepared ranging in size, type of fluorophore, fluorescence intensity and surface functional groups. Most of the fluorophores chosen for use in the preparation of SPHERO™ Fluorescent Particles are water insoluble and therefore are very stable. These fluorophores, once incorporated into the particles, do not leach and their color and fluorescence remains stable for long periods of time under proper storage conditions.

See the FLUORESCENT PARTICLE INFO on the Technical Page of the web site in order to view a PDF of the excitation and emission spectra for the fluorophores used to produce the SPHERO™ Fluorescent Microparticles.
