More help needed on betalactamase.

Thanks to Dr.Siemer for the suggestion of using a compound in
the Calbiochem catalogue, PADAC. It turns out that Calbiochem is
the only maker in North America and they dont have any and are
unable to make it these days- apparently its npot very easy to

The other compound used is nitrocefin- so far I am unable to find
out who sells that. 

If anyone can identify a source of either compound, or find 10 mg
or so in their freezer, we would be very grateful indeed.

Other info re lactamase assaying is still eagerly awaited.
With thanks
