Misc.Comments : Created by Moore, July 1995, under contract with NCBI. This strain is resistant to 100 ug/ml ampicillin. (personal communication) This is one of three bacterial expression vectors (pEX11, ATCC 37708; pEX12, ATCC 37709; and pEX13, ATCC 37710) which differ by translational reading frames and which express cro-lacZ fusion proteins regulated by the PR promoter of bacteriophage lambda. [2] This was constructed from pEX3 by ligating a synthetic oligonucleotide into pEX3 cut with XmaI and BamHI. The oligonucleotide added several unique restriction sites. [1] The recombinant fusion protein generated using this vector is not solubilized in Triton X-100 lysis procedures and is thus easily purified, resistant to proteolysis, and easily detected by direct immunoscreening. [1] Restriction digests of the clone give the following sizes (kb): EcoRI--5.8; BamHI--5.8; PstI--5.8. (ATCC staff) Medium is 1227 LB plus ampicillin.
