Analysis of Protein Structure by Cross-Linking Combined with Mass Spectrometry

Cross-linking combined with mass spectrometry is a powerful technique to study protein structure. Here, we present an optimized protocol for the preparation, processing, and analysis of a protein sample cross-linked with isotopically coded, affinity-enrichable, and CID-cleavable cross-linker CyanurBiotinDimercaptoPropionylSuccinimide using LC/ESI-MS/MS on a Thermo Scientific Orbitrap mass spectrometer.
