Peptide Mass Fingerprinting (PMF) is an analytical technique for identifying unknown protein. Proteins to be identified is first digested into peptides, whose absolute mass can be accurately analyzed ...

Perhaps no tool has been as instrumental to the proteomics revolution as the mass spectrometer. With the ability to deconvolute highly complex mixtures over a wide range of abundance levels, these ...

When researchers perform peptide mass fingerprinting on gel slices, they typically use matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) spectrometers, such as Applied Biosystems' ...
