Probability‐based protein identification by searching sequence databases using mass spectrometry data

Electrophoresis, 1999
Several algorithms have been described in the literature for protein identification by searching a sequence database using mass spectrometry data. In some approaches, the experimental data are peptide molecular weights from the digestion of a protein by ...

A statistical model for identifying proteins by tandem mass spectrometry.

Analytical Chemistry, 2003
A statistical model is presented for computing probabilities that proteins are present in a sample on the basis of peptides assigned to tandem mass (MS/MS) spectra acquired from a proteolytic digest of the sample.

Mass spectrometry combined with mass spectrometry

International Journal of Mass Spectrometry and Ion Physics, 1982
Abstract Tandem mass spectrometry (MS/MS) is a rapidly growing field of high promise for structure determination and quantitative analysis because of its sensitivity, specificity and speed. Rapid progress has been made in instrumentation, including the triple quadrupole and tandem double-focusing instruments, automated with on-line computers ...

Electrospray ionization for mass spectrometry of large biomolecules.

Science, 1989
Electrospray ionization has recently emerged as a powerful technique for producing intact ions in vacuo from large and complex species in solution. To an extent greater than has previously been possible with the more familiar "soft" ionization methods ...

Mass Spectrometry

2012
Mass spectrometry has evolved to become the biggest (in market share and total expenditure) analytical technology. It is also the analytical instrumentation sector with the biggest annual increase, thus signifying its importance and value. Mass spectrometry has become the method of choice because it offers unique characteristics not provided by other ...
