pET-28a Description
pET-28a is a prokaryotic expression vector. The C-terminal contains a 6*His tag and the N-terminal contains a 6*His tag, a thrombin digestion site and a T7 tag. The plasmid contains several commonly used restriction sites to facilitate cloning of different genes. The expression was induced by T7 RNA polymerase from host cells. The target gene was cloned into plasmid vector and controlled by strong phage transcription and translation signals. The single polyclonal site of the pET28a vector is seen above the circular plasmid map. Note: The vector sequence is encoded according to the coding rules of the pBR322 plasmid, so the T7 protein expression region is reversed on the plasmid map. The cloning and expression regions initiated by T7 RNA polymerase were also labelled in plasmid profiles. The F1 replicon of the plasmid is directed, so the viral particles containing the protein coding sequence can be produced by the T7 phage polymerase, and the protein expression can be initiated. The protein expression will be terminated by the T7 terminator sequence. The pET system is the most powerful system ever used to express recombinant protein in E. coli. It is also the most widely used system in prokaryotic expression. The plasmids can easily reduce protein expression by decreasing the concentration of inducers. Under non inducible conditions, the target gene can be completely silenced without transcribing.
