Mascot: The trusted reference standard for protein identification by mass spectrometry for 25 years

New features in Mascot 2.3

Protein Family Report

The Protein Family Summary displays search results a page at a time, allowing the results of even the largest searches to be browsed without client-side memory or browser limitations. Proteins are grouped into families using hierarchical clustering, making protein inference more intuitive and more accurate.

Percolator Support

Percolator is a utility from the University of Washington that uses machine learning to re-rank the peptide matches. The goal is to maximise sensitivity for a given false discovery rate.
