I am sorry if this posting does not belong here, but I am searching
for a company that sells a chemical ( in USA ). A friend of mine needs
it badly for his research. Apparently, this chemical is too specific
to be manufactured on a regular basis ( or atleast this is the impression
I got when I talked to the representatives at different companies ).
The chemical is:
Biotin attached to Epsilon-Aminogroup of Lysine at 32nd position of
Beta-Endorphin
phew..:-)
Any pointers are highly appreciated.
