SELDI-TOF-MS can be considered as an extension of the matrix-assisted laser desorption/ionization (MALDI)-TOF-MS method. In both cases, proteins to be analyzed are cocrystallized with UV-absorbing ...

The method involves rewiring the activity of naturally occurring shuttles to help move proteins to different parts of the cell. The team has devised a new class of molecules called "targeted ...

these 'baby' proteins could be directly identified by mass spectrometry. Improving on the more traditional method of radioactive tracing with [35 S]cysteine or [35 S]methionine metabolic ...
