TOKU-E has provided a level of customer service above and beyond any other company I've experienced.  Working closely with their sales team, I was able to optimize antibiotic selection of my recombinant yeast strains that greatly reduced the time and cost involved with strain development.  They also helped me develop several new selectable markers to enhance our strain development platform.
