Immobilized Ficin was specifically designed for cleavage of mouse IgG1 into F(ab')2 or Fab fragments. Ficin acts on bonds involving uncharged and/or aromatic amino acids. The immobilization of ficin enhances stability against denaturation, heat and autolysis. Immobilization also eliminates any potential for antibody-enzyme adducts that cause continued sample digestion. In addition to these advantages, immobilization allows the ficin to be reused.
