The ScarabXpress®-2 Protein Expression System consists of the pSX2 expression vector plus your chosen Clean Genome® E. coli host strain.
- A 3,000-fold induction range is achievable, and strong repression of the patented synthetic T5 promotor prior to induction facilitates robust healthy growth of cultures to high density.
- The high strength synthetic T5 promotor in combination with limited plasmid copy number enhances production of recombinant protein product without wasting energy on plasmid replication.
- Tight regulation of the basal level of transcription prior to induction keeps background expression low, key for target genes that are deleterious to the host.
- pSX2 is compatible with all Clean Genome® E. coli strains.
