Fluorescent Magnetic Polymer
Both Encapsulated (ME catalog codes) and Classical (MC catalog codes) superparamagnetic microspheres are synthesized using a process that results in the distribution of iron oxide crystals throughout the polymer matrix. The surfaces of Encapsulated magnetic microspheres are expected to be free of iron oxide, while the Classical version will have some exposed iron oxide. COMPEL microspheres (UMC catalog codes) are highly uniform and spherical. Fluorescent magnetic microspheres are available in these standard volumes: 1mL, 5mL, 10mL, and 100mL. See spectra for available fluorescent dyes.

Dragon Green Intensity Standard
The Dragon Green Intensity Standard is a kit consisting of five individual populations of ~8µm polystyrene-based microspheres dyed with increasing amounts of the Dragon Green fluorophore. Dragon Green is an excellent spectral surrogate for fluorescein, and is suitable for use with fluorescein filter sets.

Flash Red Intensity Standard
The Flash Red Intensity Standard is a kit consisting of five individual populations of ~8µm polystyrene-based microspheres dyed with increasing amounts of the Flash Red fluorophore. As Flash Red is spectrally similar to Cy™5, traditional red fluorophore filter sets (e.g. Cy™5/microscope, PE-Cy™5 or APC/cytometer) may be used with this standard.
