In addition to Bangs Labs there is
 
Duke Scientific Corp
2463 Faber Place,
P.O. Box 50005,
Palo Alto CA 94303 USA
(800) 334-3883 or (415) 424-1177,
(They carry fluorescent beads, SINGLE colors, in various sizes 0.05 to 2
microns, $95 per 7 ml of 1% solids, no surfactant or preservative
Green 469/509 nm
Red 541/611 nm
Blue 365/446nm, 388/446nm, 412/473nm)
 
and I also have an address for another bead company, but I don't know if
they make fluorescent beads:
Interfacial Dynamics
4814 NE 107th St.
Portland OR 97220 USA
(503) 256-0076.
 
As of a year or so ago, Bangs distributed Estapor brand "luminescent"
beads from Rhone-Poulenc, with several dyes available.
 
I am curious how these compare with Molecular Probes' beads.

An alternative to Mol. Probes beads are those from other companies.
They can be much cheaper at times, and provide quite a bit more
information about the homogeneity (or not) of the beads you buy. There
are two companies that specialize in the beads, but I could only dredge
up one of them (the other is buried somewhere around here and refers
to a company named Interfacial Sciences or something similar in the West
USA).
Sorry to be inconclusive, but here is the other alternative...
