Enzyme immobilization: The protease enzyme was successfully immobilized onto dicyclohexylcarbodiimide (DCC)-activated metal-organic frameworks (MOFs). After separation by nano-LCMS2 (liquid chromatography-mass spectrometry), detection, and database searching the protein digestion efficiency of trypsin-MOF was comparable to traditional in-solution digestion (see figure). Furthermore, the trypsin-MOF was reusable.
