Topo Baculovirus Expression Kits
The DES® TOPO® TA Expression Kit offers one-step cloning of PCR products directly into an inducible DES® expression vector. The kit uses the linearized, topoisomerase I-activated pMT/V5-His-TOPO® vector for fast and easy cloning and subsequent high-level expression. Topoisomerase activation of this vector allows PCR products to be ligated in just 5 minutes on your bench top to produce >85%recombinants. The pMT/V5-His-TOPO® vector has all of the features of the pMT/V5-His vector to simplify protein expression, detection, and purification of recombinant proteins in Drosophila S2 cells.

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...

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 ...
