The only next-generation bacterial expression system
Vmax cells are derived from one of the fastest growing organisms on earth: the gram-negative, non-pathogenic marine bacterium, Vibrio natriegens.
Vmax doubles two times faster than E. coli and generates significantly greater amounts of biomass and protein per volume of cells.
Simply stated, Vmax X2 results in much larger amounts of soluble protein much faster.

VMax X2 competent Cells
A New Host System with Advantages Over E. coli
Vmax X2 Competent Cells are engineered to retain the benefits of traditional bacterial protein expression systems — low cost, easy to grow, high transformation efficiency, and compatible with plasmids and antibiotics already in widespread use.
With an accelerated doubling time, Vmax X2 shortens protein expression workflows by one day and generates more soluble protein in less time than E. coli.
Additionally, Vmax naturally has low immunogenicity with endotoxin levels 100-times lower than E. coli, making it an ideal host system for protein purification.
Incorporates Into Your Existing Workflow
Vmax X2 is compatible with plasmids and antibiotics commonly used with bacterial expression systems such as E. coli BL21 (DE3) and has a transformation efficiency rivaling the best alternative protein 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 Enriched Growth Media (recommended for rapid growth and greatest accumulation of biomass). In addition, Vmax X2 cells can be induced over a wide range of timepoints, from an OD600 of 0.2 to over 1.0, without loss of final protein yield, dramatically increasing workflow flexibility.
