2.5.1.22
Cell lysate is loaded onto a HiTrap chelating column charged with Ni2+. The enzyme is eluted with an imidazole gradient (50-250 mM) at pH 8.0. The protein is loaded onto a Superdex 200 column equilibrated with 20 mM Tris-HCl and 150 mM NaCl. Thrombin is added to combined fractions containing SpmSyn to remove the His-tag. The protein is further purified to homogeneity by ion-exchange chromatography.
