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...

To permit simultaneous long-term tracing of mixed-cell populations using different fluorescent colors, we have developed a probe whose applications should be similar to those of CFDA SE (commonly called CFSE). Cells labeled with our SNARF-1 carboxylic acid, acetate, succinimidyl ester have orange-red fluorescence that can be easily distinguished from that of cells loaded with green-fluorescent tracers such as CFDA SE.

The CaptureSelect™ IgG-CH1 affinity matrix recognizes the CH1 domain of human IgG antibodies, which enables purification of all subclasses (1, 2, 3 and 4) of human IgG and Fab fragments, independent of the light-chain isotype and source material. Due to its unique selectivity for the CH1 domain, no co-purification of free light-chain contaminants will occur. Since no cross-binding is observed for bovine IgG, the product can be used for the purification of IgGs and antibody fragments in the presence of fetal calf serum.
