ProteomicsFormaldehyde derivatization, a Side Reaction During Filter-Aided Sample Preparation
The filter-aided sample preparation (FASP) method has been commonly used for proteomic sample preparation due to its high efficiency and convenience. Herein, we report an overlooked side reaction during FASP method, resulting in a mass increment of 12 Da. We confirmed that the side reaction is cause...

ProteomicsN-Terminal Protein Sequencing by Nicotinic Acid Derivatization and MS Analysis
Most MS-based workflows for N-terminal protein sequence analysis rely on the modification of primary amines at the protein N-terminus and lysine residues, in many cases through dimethylation. However, incomplete dimethyl labeling and undesired side reactions have been reported previously and were al...

ProteomicsHelical superstructures between amyloid and collagen VI in heart derived fibrils from a patient with Light Chain Amyloidosis
We investigated the N- and C-terminome of the LCs proteoforms in fibrils extracted from the hearts of a patient affected by AL amyloidosis, using a proteomic approach based on N- and C-terminal residues derivatization, followed by mapping of fragmentation sites on the structures of fibrillar LCs
