Complex research endeavors such as the investigation of cell signaling pathways, disease state characterization, and biomarker Bottom-up proteomics is the most widely used technique, but does not provide the holistic view of protein structure achieved using the top-down approach. This alternative method directly analyzes intact proteins and, by maintaining their structural integrity, MS-based top-down proteomics enables the mapping of PTMs with full sequence coverage, as well as quantification of specific proteoforms. 2014-04-07 · Top-down proteomics with mass spectrometry imaging: a pilot study towards discovery of biomarkers for neurodevelopmental disorders.

Top-down proteomics is a method of protein identification that either uses an ion trapping mass spectrometer to store an isolated protein ion for mass measurement and tandem mass spectrometry (MS/MS) analysis or other protein purification methods such as two-dimensional gel electrophoresis in conjunction with MS/MS. Top-down proteomics is capable of identifying and quantitating unique proteoforms through the analysis of intact proteins.

Achieve ultra high resolution of multiple proteins Top-down proteomics challenges spectral detection because each intact protein has a higher number of charge states, isotopic peaks, and co-eluting modified forms than bottom-up peptides. Top-down Proteomics is the analysis of intact proteins by mass spectrometry. This technique allows for exact mass calculations of protein analytes and is thus a reliable method for characterizing proteoforms.

The rise of the "Top Down" method in the field of mass spectrometry-based proteomics has ushered in a new age of promise and challenge for the characterization and identification of proteins. Injecting intact proteins into the mass spectrometer allows for better characterization of post-translational modifications and avoids several of the serious "inference" problems associated with peptide-based proteomics.
