The BL21 Gen-X cells were created through careful cycles of mutagenesis, enrichment, and testing, resulting in a novel and more powerful protein expression strain. By reducing the growth rate and optimizing other characteristics, Genlantis scientists have produced BL21(DE3) cells that are qualitatively distinct from previous generations of BL21(DE3) E. coli.

The results are striking: BL21 Gen-X, along with the powerful Gen-X Induction Enhancer, will express more of what you want, and less of what you don't want. For example, the BL21 Gen-X cells are able to express proteins that are not expressed or detected at all using other popular BL21 cells or kits. (see Figure 2, lanes 2)
With the BL21 Gen-X Competent E. coli Expression Kit, there is now a better way to express your recombinant proteins. The resulting higher yields and lower background will make downstream purification and processing of your recombinant proteins much easier, saving you significant time and money.
