  1. fliC is inserted in pUC19 vector→pUC19-FliC
  2. ExSite PCR
  3. design insert(6×Histidine-Tag)
  4. Lagation pUC19-FliC vector and insert(flic+6×His-tag)
  5. GelCheck


  • ExSite PCR
  • design primer
  • Among the code of FliC, we selected five fragment codes from the outside part of the target filament, then designed each primers(207,228,240,252,267). Mounted pUC19-FliC to pUC19-FliC-vector.

  • [Reaction Conditions]
    • Template 1μL
    • Primer(Foward and Reverse) 5μL
    • 10×buffer 10μL
    • dNTPmix 10μL
    • vent 1μL
    • dH2O 68μL


  • design insert
    • six histidine loop peptide ("His-loop")
    • -Ser-Ser-His-His-His-His-His-His-Ser-Ser
    • encoded by the oligo 5'-TCT-TCT-CAT-CAT-CAT-CAT-CAT-CAT-TCC-TCC-3'
    • and anti oligo 5'-GGA-GGA-ATG-ATG-ATG-ATG-ATG-ATG-AGA-AGA-3'
    • restriction site (N termimal: EcoRⅠ,C terminal: NcoⅠ


  • Ligation pUC19-FliC vector with insert.
  • [Reaction Conditions]
    • insert 2μL
    • pUC19-FliC vector 2μL
    • ×5 Ligase Buffer 4μL
    • Ligase 1μL
    • dH2O 11μL
