This product line was developed for general laboratory use. Applied Microspheres can offer many batches of particles with a wide variety of diameters, that can be custom dyed with different fluorescent colours and intensity levels as required. The dyes are incorporated during the polymerisation process, which prevents dye leakage. Applied Microspheres’ unique technology ensures exceptionally small fluorescence C.V.’s. Dispersion in both aqueous media or air are possible without degradation of their fluorescent properties. They are available as aqueous suspensions or as dry powder. The aqueous medium for the suspensions is specially formulated to prevent the formation of agglomerates and for long-term stability. They can be stored at room temperature.
The fluorescent microspheres can be detected with a flow cytometer, epifluorescence microscope, confocal microscope, fluorescence spectrophotometer, amongst others. They can also be detected using a mineral light or black light and can be observed directly in the matrix or media being tested, or they can be collected on membrane filters for examination by microscope. For some applications, the polymer microspheres can be dissolved and the fluorescent dyes measured directly.
