pET Expression Systems and pET
pET Expression Systems and pET Expression Systems plus Competent Cells provide core reagents needed for target gene cloning and expression.

Components: pET Expression Systems
Components for pET Expression Systems are similar for all systems unless otherwise stated with the specific pET Expression System description. pET Expression Systems include:
• 10 µg pET vector DNA (for each indicated plasmid)
• 0.2 ml BL21 Glycerol Stock
• 0.2 ml BL21(DE3) Glycerol Stock
• 0.2 ml BL21(DE3)pLysS Glycerol Stock
• 0.2 ml Induction Control Glycerol Stock

Components: pET Expression Systems plus Competent Cells
pET Expression Systems plus Competent Cells contain all of the components of the specific pET Expression System, as well as the following additional components, unless otherwise stated with the specific pET Expression System description:
• 0.2 ml NovaBlue Competent Cells
• 0.2 ml BL21(DE3) Competent Cells
• 0.2 ml BL21(DE3)pLysS Competent Cells
• 2 × 0.2 ml SOC Medium
• 10 µl Test Plasmid

These components are sufficient for up to 10 transformations in each host.

Purification and Detection Reagents
Purification and detection reagents are available separately. For complete product descriptions and ordering information, refer to the Protein Purification and Antibodies, Conjugates & Detection Tools chapters.

pET Expression System 21
The pET Expression System 21 contains 10 µg each of the four versions of pET-21 (pET-21a–d(+)). pET-21(+) is a transcription vector designed for expression from bacterial translation signals carried within a cloned insert. It therefore lacks the ribosome binding site and ATG start codon present on the pET translation vectors. A C-terminal His•Tag^® sequence is available. Note that the sequence is numbered by the pBR322 convention, so the T7 expression region is reversed on the vector map, TB036VM.
