tract-tracing with biotinylated cholera toxin?

   I would like to know if anyone has used List Biological's (or anybody
else's, for that matter) cholera toxin subunit B conjugated to biotin as a
neuronal tracer. I have had good results with List's unconjugated cholera
toxin visualized with immuno, and with gold-conjugated cholera toxin
visualized with silver intensification, but have never tried the biotin
labeled cholera toxin.
   I would like to do some double labeling experiments using the
biotin-conjugated tracer in conjunction with other tracers. But first I
would like to know if anyone has some suggestions on concentrations,
amount to inject, what buffer to dissolve it in, etc.
