Looking for dyd sources

[Doug McDonald]

I'm looking for sources of fluorescent dyes that can be attached to (mostly)
amine groups. I have the Molecular Probes catalog, but surely there are other
suppliers out there. I need names and phone numbers. 

I'm looking particularly for dyes that I can attach to amine groups
attached to silica surfaces. The proteins (with different dyes attached)
would sit on the surface. I need very stable dyes.
