Have you got any favorite single copy number vectors? say 1-3 copies per 
chromosome? I have been using pMU2385 but it is a bit of a pain because it is 
13 kb. I want to be able to clone large, say 20kb fragments onto a vector 
which can then be introduced into Salmonella typhimurium. Any E.coli vector 
should do. Any help gratefully recieved
