Gangliosides from bachem?

[Erik A.J. Miljan]

I am using specific gangliosides GM1, GQ1b.... for signal transduction
studies. I found them in the freezer and they are purified by bachem,
Torrance, California.  The only bachem I know is in Switzerland.

Does anybody have a fax #, Tele# or e-mail for the bachem in California
so I can check the purity?

Thanks for your help
Cheers
