Champion™ pET100 Directional TOPO® Expression Kit with BL21 Star™ (DE3) One Shot® Chemically Competent E. coli

Category: Products & Services > Kits & Assays > Protein Expression Kits > Bacterial Expression Kits

The Champion™ pET Expression System yields the highest-level protein production in E. coli . During expression, your protein of interest can reach levels greater than 50 percent of total cellular protein. Based on T7 expression vectors originally developed by Studier and colleagues (1-3), high-level expression is achieved because the T7 RNA polymerase is more processive than native E. coli RNA polymerase and is dedicated to the transcription of your gene of interest. Protein production is further enhanced in the system by the expression strain BL21 Star™ E. coli , which significantly improves ...

Champion™ pET SUMO Expression System

Category: Products & Services > Kits & Assays > Protein Expression Kits > Bacterial Expression Kits

The Champion™ pET SUMO Expression System produces the highest levels of soluble protein in E. coli . It utilizes a small ubiquitin-related modifier (SUMO) fusion, belonging to the growing family of ubiquitin-related proteins, to enhance the solubility of expressed fusion proteins. In contrast to ubiquitin, SUMO is involved in the stabilization and localization of proteins in vivo . After expression, the 11 kd SUMO moiety can be cleaved by the highly specific and active SUMO (ULP-1) protease at the carboxyl terminal, producing a native protein*. The Champion™ pET SUMO Protein and Peptide Expres...

pBAD202 Directional TOPO® Expressions Kit

Category: Products & Services > DNA Vectors, Clones, Purified Nucleic Acids & Libraries > DNA Vectors > Bacterial Expression Vectors

Using restriction enzymes to clone your gene into an expression vector often forces you to compromise the final sequence of your insert (Figure 1A), especially when there are no useful restriction sites close to your genes coding sequence. This may result in suboptimal spacing of expression elements or incorporation of non-native amino acid residues, which can reduce your expression levels and/or cause the production of non-functional protein. In addition to being a more effective way to clone, TOPO® Cloning eliminates these potential expression problems. TOPO® Expression Vectors enable you to...
