ScarabXpress®-2 system, our second-generation protein expression system, consists of the pSX2 expression plasmid and ANY Clean Genome® E. coli host strain. In side by side comparisons, the ScarabXpress®-2 system protein expression system gave up to 36x higher yields than standard expression vectors with wild-type E. coli strains
