Protein Expression with Ultra-High Yields

Vmax™ X2 cells are a next-generation bacterial expression system engineered from the gram-negative, non-pathogenic marine bacterium, Vibrio natriegens, which is amoung the fastest growing organisms on earth. Vmax™ X2 cells retain all the benefits of traditional bacterial expression systems while generating significantly greater amounts of protein. 

• Exceptional growth rates, with a doubling time less than 14 minutes (up to 2x faster than E. coli) 

• Protein yields are 2–4x higher than E. coli due to high biomass production and growth rates 

• Protein expression can be induced at a wide variety of OD600readings (0.1 to over 1.0) 

• Compatible with commonly used plasmids and antibiotics 

• 100x reduction in endotoxin levels compared to traditional  coli strains
