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 CyanurBiotinDimercapto PropionylSuccinimide using LC/ESI-MS/MS on a Thermo Scientific Orbitrap mass spectrometer.
