Bacterial expression vectors

[Darrin D Simmons]

Hi all,
    We are currently having problems expressing a particular protein in
bacterial systems with the pROex and pET series expression vectors ( which
have usually worked well for us).  As a result, we are looking for bacterial
expression vectors from other companies - in particular, ones that would
allow the addition of an epitope tag (like a his tag but not exclusively). A
site with a list of vectors or just a "this one from company X works great
for us" would be appreciated. You can reply to the group or to the email
address below.

Thanks in advance,
