Enzymes Buffer Temperature Purpose
EcoRI, XbaI Low 37°C To create a "Front Vector"
EcoRI, SpeI Low 37°C To create a "Front Insert"
SpeI, PstI Medium 37°C To create a "Back Vector"
XbaI, PstI Low 37°C To create a "Back Insert"
EcoRI, PstI Promega® Buffer H 37°C To excise entire insert or validate part size


Davidson Buffers [10 mM Tris-HCl pH 7.5, 10 mM MgCl2, 0.1 mg/mL BSA, X mM NaCl]

  • 0 (zero), 0 NaCl
  • Low, 50 mM NaCl
  • Medium, 100 mM NaCl
  • High, 150 mM NaCl
