Vmax™ X2 is a novel, fast-growing bacterial strain designed and optimized for high-level recombinant protein expression. Vmax™ cells are derived from the gram-negative, low endotoxin, non-pathogenic marine bacterium, Vibrio natriegens. With a doubling time twice that of E. coli and the ability to generate greater amounts of biomass per volume of cells, Vmax™ X2 results in larger amounts of soluble protein faster.

Vmax™ X2 cells are compatible with plasmids and antibiotics commonly used with bacterial expression systems such as E. coli BL21(DE3) and have a transformation efficiency rivaling the best alternative bacterial expression strains.

Built with a tightly controlled, IPTG-inducible T7 promoter system, Vmax™ X2 cells can be cultured using routine growth medium, as well as commercial auto-induction media, or our Vmax™ X2 enriched growth medium (recommended for rapid growth and greatest accumulation of biomass). In addition, Vmax™ cells can be induced over a wide range of time points, from an OD600 of 0.1 to over 1.0, without a loss of final protein yield, dramatically increasing workflow flexibility.
