Label-Free Optical and Mass Spectrometry Methods

2 Label-Free Optical and Mass Spectrometry Methods 

Label-free optical techniqnes for detecting bound proteins on microarrays have been recently reviewed. The advantage of these methods over labeling methods is that the native form of the analyte is preserved. These methods include SPR, surface-enhanced laser desorption/ionization mass spectrometry (SELDI-MS), atomic force microscopy and fiber-optic methods.
