Trypsin‐Immobilized Metal–Organic Framework as a Biocatalyst In Proteomics Analysis

Enzyme immobilization: The protease enzyme was successfully immobilized onto dicyclohexylcarbodiimide (DCC)-activated metal–organic frameworks (MOFs). After separation by nano-LC-MS2 (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. Detailed facts of importance to specialist readers are published as "Supporting Information".
