pGEM®-3Z Vector

The pGEM®-3Z Vector is intended for use as a standard cloning vector, as well as for the highly efficient synthesis of RNA in vitro. The vector carries the lacZ α-peptide and the multiple cloning region arrangement from pUC18 allowing selection of recombinants by blue/white screening. In addition, the vector contains both the SP6 and T7 RNA polymerase promoters flanking the multiple cloning region.

The pGEM®-3Z and pGEM®-4Z Vectors are essentially identical except for the orientation of the SP6 and T7 promoters.
