* Excitation (Ex) and emission (Em) maxima in nm. FluoSpheres beads are supplied as aqueous suspensions containing 2% solids and 2 mM sodium azide, except for the 0.04 µm microspheres (†), which are supplied as aqueous suspensions containing 5% solids without preservatives; the 1 µm microspheres for tracer studies (‡), which are supplied as aqueous suspensions containing 1010 microspheres per mL and 0.02% thimerosal; and the europium luminescent microspheres, which are supplied as aqueous suspensions containing 0.5% solids and 2 mM sodium azide. All sizes fall within a narrow range as discussed in Microspheres—Section 6.5. Sizes indicated in the above tables are nominal and may vary from batch to batch. Actual sizes, as determined by electron microscopy, are specified on the product labels.
