Abstract

Top-down mass spectrometry is an emerging technology which strives to preserve the post-translationally modified forms of proteins present in vivo by measuring them intact, rather than measuring peptides produced from them by proteolysis. The top-down technology is beginning to capture the interest of biologists and mass spectrometrists alike, with a main goal of deciphering interaction networks operative in cellular pathways. Here we outline recent approaches and applications of top-down mass spectrometry as well as an outlook for its future.
