Cell-Free Expression Kits & Assays
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 ...

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 LIVE/DEAD® Fixable Dead Cell Stain Kit employs an amine-reactive fluorescent dye to evaluate mammalian cell viability by flow cytometry. In cells with compromised membranes, the dye reacts with free amines both in the cell interior and on the cell surface, yielding intense fluorescent staining. In viable cells, the dye's reactivity is restricted to the cell-surface amines, resulting in less intense fluorescence. The difference in intensity between the live and dead cell populations is typically greater than 50 fold, and this fluorescence intensity discrimination is completely preserved fol...
