MUF-a.a. source?

[Christian Belanger]

Hello everybody,

I'm looking for fluorigenic compound MUF-a.a. (Methylumbelliferone conjugate
with an amino acid).  I absolutely need MUF (and not other, as MCA).  I
found in an old article that the German cie Serva Feinbiochemica supplied
this compound.  Is this cie exist in U.S. or Canada?  Is other cie supplied
MUF-a.a. conjugate?  E-mail me your answers.

Thank's
