I'd like to second Wolframs's caution. Vanc is the only antibiotic that
kills some things and is used for serious clinical infections (read life and
death). Resistant strains are appearing, although Vanc resistance hasn't
migrated to MRSA, yet. I don't think it would be wise to start using Vanc
as a marker for routine experiments.
