  • vector for the expression of proteins in E. coli, the plasmid allows to fuse a Strep-tag to the N-terminus of the expressed protein
  • host: E. coli BL21(DE3)/pLysS, expression of the desired protein is induced by the addition of 1 mM IPTG to the culture
  • in E. coli: ampicillin resistance
  • based on pET3C
  • sequencing primer:
    • CD13: 5’-AAACATATGGCTAGCTGGAGCCACCCGCAGTTC -3’
    • NP20: 5’-GCAGCAGCCAACTCAGCTTCCTTTCGGGC-3’
  • important: EcoRI, although mentioned in the MCS, is not unique!
