WANTED: anti gamma glutamyl carboxyl group

[Willy Flegel]

I am interested to investigate gamma-glutamyl carboxylase activity in vivo 
and in vitro.

Does anybody know about the possibility 
to raise antibodies against the epitope of gamma-glutamyl carboxyl group in 
general (i.e., not against the carboxylation domain of any of the known  
carboxylated proteins in particular).

Are such polyclonal/monoclonal antibodies published 
or (commercially) available?

Any information is appreciated.
