Description

Ultrapure 1,5 diaminonapthalene (DAN) is an important matrix used in peptide and protein analysis by matrix assisted laser desorption ionization (MALDI) mass spectrometry. The matrix is effective in promoting reduction of disulfide bonds in the gas phase, which greatly facilitates analysis of proteins and peptides containing disulfide linkages.
