                 ISOTOPICALLY LABELLED COMPOUNDS
          ------------------------------------------------


I am seeking to identify other investigators interested in 

              _____________________________________

               A CONSORTIUM-type GRANT APPLICATION 
              _____________________________________


to order the custom synthesis of "L" amino acids with a SINGLE 13-C label in 
the peptide backbone (carbonyl) group (see list of expensive or unavailable
compounds below).

At this point, NO COMMITMENT to join such an application is being requested,
or to join in the purchase of anything.  I am merely trying to identify
investigators with A POTENTIAL INTEREST so that I may target further
information and future correspondence.

If you are interested in the results of this posting, or in receiving
further correspondence in regards to this matter, PLEASE RESPOND BY EMAIL.

...........................................................................

If you have related or "slightly" different interests  . . . 

(e.g. labelled 'aib', D-amino acids, or an 15-N label in the peptide group), 

please also respond and indicate your specific interest.  If you wish these 
compounds to be prepared as Fmoc or t-Boc derivatives, please indicate this 
and your preference (Fmoc or t-Boc) as well.
