ProUSER vectors

The ProUSER vector collection is a set of vectors that facilitates fast and efficient USER cloning, without the need for PCR amplifying the backbones or promoter sequences.

The vector-backbones are based on the widely used pSEVA collection, which enables easy swapping of antibiotic resistance cassettes and origin of replications. A variety of ProUSER reporter vectors containing an inducible promoter and a fluorescent protein (either GFP or mCherry) are further available for fast screening of the applicability of various promoters in bacteria. The vectors are currently available upon request from the authors.
