I'm starting with yeast and some of my plans call for sphaeroplasts.

Current Protocols in Molecular biology gives a protocol for doing this
that uses Zymolase. Somewhere I read that ICN is supposed to have that 
stuff. Unfortunately I cannot find it in their catalogue (91/92 edition).
Instead they offer several items called 'Yeast Lytic Enzyme' and say that
these are useful for preparing yeast sphaeroplasts. So here goes :

Is Zymolase obsolete ?

Is Yeast Lytic Enzyme the way to go ? Does that mean a change in the
protocol (units/ml etc.) ?

What is the 'state of the art' way of preparing sphaeroplasts.

Any help is appreciated.
