Mascot is a software search engine that uses mass spectrometry data to identify proteins from peptide sequence databases. [ 1 ] [ 2 ] Mascot is widely used by research facilities around the world. Mascot uses a probabilistic scoring algorithm for protein identification that was adapted from the MOWSE algorithm.
Web-based mass spectral database that comprises a collection of high and low resolution tandem mass spectrometry data acquired under a number of experimental conditions. MZmine Open source: An open-source software for mass spectrometry data processing, with the main focus on LC-MS data. OmicsHub Proteomics
OpenMS provides a set of over 100 different executable tools than can be chained together into pipelines for mass spectrometry data analysis (the TOPP Tools). It also provides visualization tools for spectra and chromatograms (1D), mass spectrometric heat maps (2D m/z vs RT ) as well as a three-dimensional visualization of a mass spectrometry ...
Mass spectrometry is a scientific technique for measuring the mass-to-charge ratio of ions. It is often coupled to chromatographic techniques such as gas-or liquid chromatography and has found widespread adoption in the fields of analytical chemistry and biochemistry where it can be used to identify and characterize small molecules and proteins ().
Mass spectrometry (MS) is an analytical technique that is used to measure the mass-to-charge ratio of ions.The results are presented as a mass spectrum, a plot of intensity as a function of the mass-to-charge ratio.
A mass chromatogram is a representation of mass spectrometry data as a chromatogram, where the x-axis represents time and the y-axis represents signal intensity. [1] The source data contains mass information; however, it is not graphically represented in a mass chromatogram in favor of visualizing signal intensity versus time.
The mass of b 2-ion = mass of two amino acid residues + 1. Table 2. Mass of b2-ions in peptide fragmentation [16] Identify a sequence ion series by the same mass difference, which matches one of the amino acid residue masses (see Table 1). For example, mass differences between a n and a n-1, b n and b n-1, c n and c n-1 are the same.
Label-free quantification is a method in mass spectrometry that aims to determine the relative amount of proteins in two or more biological samples. Unlike other methods for protein quantification, label-free quantification does not use a stable isotope containing compound to chemically bind to and thus label the protein. [1] [2]
