But where are you getting your methicillin from? It was withdrawn by
Sigma two years or so ago because of, I believe, world wide concerns
over MRSA etc. and was no longer being prescribed and therefore
manufacture was also stopped.

Do you get satellites with Oxacillin or Nafcillin and do you mix with
Ampicillin or use as is?

The problem with being on the cutting edge is that you occasionally get 
sliced from time to time....
