Mass spectrometry reveals the chemistry of formaldehyde cross-linking in structured proteins

Formaldehyde (FA) is a popular cross-linking reagent, but applying it for cross-linking mass spectrometry (XLMS) has been largely unsuccessful. Here, the authors show that cross-links in structured proteins are the product of two FA molecules and identify hundreds of FA cross-links by XLMS in vitro...

Description
Summary:Formaldehyde (FA) is a popular cross-linking reagent, but applying it for cross-linking mass spectrometry (XLMS) has been largely unsuccessful. Here, the authors show that cross-links in structured proteins are the product of two FA molecules and identify hundreds of FA cross-links by XLMS in vitro and in situ.
