aminocoumarin immunoprecipitation - looking for primary antibody (Aug/22/2006 )

Hi All,

I recall seeing a paper awhile ago, where some folks used the 7-dimethyl (or possibly diethyl) aminocoumarin moiety in a fluorescent probe as the basis for an immunoprecipitation, but I can't find such an antibody anywhere (and can't remember the paper).

Anybody know where I can get an antibody to 7-dimethylaminocoumarin?

Thanks.

I did google search and could not find any commercial product on antibody against this fluorophore. I know FITC can be used as a hepten for immunoprecipitation if you can use it.
