Sugar-derivatized latex beads

[jmahoney at molbiol.ox.ac.uk]

Dear Netters-

	Does anyone know of a commercial source of sugar-derivatized 
fluorescent latex beads (e.g., fluorescent Gal-beads, Lac-beads, Man-
beads,etc.)?  Alternatively, does anyone have any of these which they've 
synthesized, and would be willing to part with small samples?

	Thanks in advance.
