Abstract
Peptide and carbohydrate biochips can be assayed with MALDI mass spectrometry. Self-assembled monolayers (SAMs) that are modified with ligands provide a platform for identifying selective protein-ligand and enzyme-substrate interactions. MALDI provides a rapid and sensitive method for detection and avoids the need to label protein analytes with fluorescent or radioactive tags. The picture shows the mass spectrum of a SAM presenting a carbohydrate.
