Topo Mammalian Expression Kits

pSecTag/FRT/V5-His© TOPO® TA Expression Kit

Category: Products & Services > DNA Vectors, Clones, Purified Nucleic Acids & Libraries > DNA Vectors > Mammalian 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...
