Description
The pSX2 expression vector is designed to be combined with your chosen Clean Genome® E. coli host strain to produce the robust ScarabXpress®-2 Protein Expression System.
- 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.
- If pSX2 is used with strains other than Clean Genome® we strongly suggest testing the strain with the Insertion Sequence (IS) Detection Kit to verify that no transposable elements are present.
