The pCMVTnT™ and pTnT™ Vectors are designed for convenient expression of cloned genes in vitro or in vivo. SP6 and T7 promoters allow expression from SP6- or T7-based coupled in vitro transcription/translation systems. The presence of RNA phage promoters also allows highly efficient synthesis of RNA in vitro. Both vectors contain a 5´ β-globin leader sequence, and the pTnT™ vector also contains a synthetic poly(A)30 tail; these elements have been shown to enhance expression of certain genes. The multiple cloning site provides a selection of restriction sites.
For in vivo expression, the pCMVTnT™ Vector contains a CMV enhancer/promoter region, which allows strong constitutive expression in many cell types.
