pET-43.1 Ek/LIC Vector Kit
pET Expression Systems and pET Expression Systems plus Competent Cells provide core reagents needed for target gene cloning and expression.The pET-43.1 vectors incorporate the Nus•Tag fusion partner and are also compatible with the trxB/gor mutant Origami, Origami 2, Origami B, Rosetta-gami, Rosetta-gami 2, and Rosetta-gami B strains, which facilitatedisulfide bond formation in the cytoplasm (Davis 1998). Disulfide-bonded proteins maybe obtained by employing the combination of a pET-43.1 or pET-44 vector and these trxB/gor host strains. Unfused proteins can be produced by using the Nde I cloning site.

Directional PCR cloning into the most powerful E. coli expression vectors

The pET-43.1 series of vectors are designed for cloning and high-level expression of peptide sequences fused with the 491 aa Nus•Tag™ protein. Vector encoded sequence can be completely removed by cleaving the Nus•Tag fusion protein with enterokinase. Note that the sequence is numbered by the pBR322 convention, so the T7 expression region is reversed on the vector map, TB318VM. The f1 origin is oriented so that infection with helper phage will produce virions containing single-stranded DNA that corresponds to the coding strand.

The various pET Ek/LIC Vectors are shown below. Configurations of the pCDF-2 and pRSF-2 Ek/LIC Vectors, which are designed for coexpression, are also shown. For additional information about the LIC method and Ek/LIC primer design, refer to the previous section, The LIC Method. Ek/LIC vectors for insect and mammalian expression are also available.
