I've never used either but have liked the methodology behind the
transposon since someone came up with the idea for cosmids many years
ago. The other point is to remember that there are always a lot of posts
a year from people asking for help sorting out problems with the
exoIII/mung bean method. It may be worth scanning the archives for this
news group before you decide.


My mind's made up. Don't confuse me with the facts!
