The place to buy cholera toxin products is:

List Biological Laboratories, Inc.
501-B Vandell Way, Campbell, California
95008-6967 U.S.A.
(408) 866-6363
(800) 726-3213
FAX: (408) 866-6364


They sell the cholera toxin subunit B for retrograde tracing and a
goat polyclonal antibody against it. They also sell the toxin conjugated
to HRP, 
or biotin, or colloidal gold,or several of the more popular fluorochromes.
I personally favor the colloidal gold conjugated tracer, as it can be
visualized with
a simple silver intensification. Hope this helps.
