Polychromatic (PC Red) Red Microspheres

Polysciences’ Fluoresbrite Polychromatic Red Microspheres are internally dyed, monodisperse polystyrene beads exhibiting a broad, excitable red fluorescence; they come as aqueous suspensions (nominal 2.5% solids) in multiple diameters (e.g. 0.5, 1.0, 2.0, 6.0 µm). These microspheres are stable, with narrow fluorescence CVs, leaving the surface available for adsorbing ligands, making them useful for assays, tracer particles, phagocytosis work, and multi-color optical setups.
