pET303/ CT-His Description
PET303/CT-His pET303-CT-His is an Escherichia coli pET expression plasmid.The Champion pET302/NT-His and pET303/CT-His Vector Kit is designed for cloning a gene of interest via restriction enzyme(s) and ligase (REaL) and subsequent high-level expression from the strong bacteriophage T7 promoter. In addition to the T7 promoter, each vector contains only the necessary functional elements and an N- or C-terminal 6xHis tag (pET302/NT-His and pET303/CT-His, respectively) for convenient purification and detection (Figure 1). Expression levels obtained from these vectors may be higher than those obtained from another suppliers pET vector (Figure 2). To maximize expression, use with MagicMedia E. coli Expression Medium.
