Surface-Enhanced Laser Desorption/Ionization-Time of Flight Mass Spectrometry

**Semantic type:** Laboratory Procedure

**Definition:** A time-of-flight (TOF) mass spectrometry method that is used to analyze protein mixtures by selectively adsorbing proteins onto a chemically modified surface, then desorbing and ionizing them using a laser.

**Synonyms:** - SELDI-TOF - SELDI-TOF-MS
