Mass spectroscopy of proteins

[Eric R. Hugo]

I have read that it is possible to use fast atom bombardment, 
electrospray,
or laser desorption mass spectrometry to accurately determine 
molecular 
weights of proteins.  Is anyone aware of contract services that would 
do 
this for a protein of about 10,000 mw?  I would like to use it to rapidly
characterize mutant recombinant proteins.  Thanks for your help.

Washington University School of Medicine's Protein Chemistry Lab has 
an electrospray mass spec.  I'm not sure if they do contract work 
outside the university but I do know that they contract within the 
university.
