Hi there, this is a first-time post so please bear with me.

A while ago I read on this group that someone was using a combination of
ampicillin and methicillin in their LB plates to select for E. coli
transformants. This was a cheaper alternative than using carbenicillin.
I've ordered the methicillin but can't remember what concentrations of
each to use!  
Could someone please help? Thanks.
