BL21 Gen-X™ Competent E.coli Expression Kit

More of your recombinant proteins with less background

The BL21 Gen-X™ E. coli is a next generation genetic variant of the standard BL21(DE3) strain. The BL21 Gen-X™ strain was created through careful cycles of mutagenesis, enrichment, and testing to provide a new and more powerful protein expression bacteria.

These special E. coli cells have a slower growth rate and characteristics that lead to significantly higher recombinant protein expression, while exhibiting much lower endogenous or background bacterial proteins. The results are clear, the BL21 Gen-X™ strain, along with the powerful Gen-X™ Induction Enhancer, will express more of what you want, and less of what you don’t in vivo.
