Seeking taurocholate source

[bradley turner]

Dear bionetters,

I would like to know if anyone would be able
to suggest acommercial source of relatively
pure (>99%) sodium taurocholate for the
preparation of model bile solutions?  My
former source (Fluka) has discontinued its
high purity preparation and the usual
chemical suppliers don't seem to produce
anything above 97%. And the usual lipid
suppliers (Avanti or Matreya) have no
information.  I would be interested in
gram quantities.

Thank you,
Brad Turner
