See what’s possible with ProSightPD.
ProSightPD can be used in a wide range of applications across diverse research fields.
Modification Identification
Search modifications with confidence. By using annotated modifications from UniProt™ or custom XML files, ProSightPD assigns only modifications with empirical evidence for their existence. Unknown mass shifts can also be used to account for mass differences and to assign additional fragmentation ions.
Cleavage/Truncation Identification
Look for endogenous cleavages and protein truncations. Cleavage sites can be determined on the N-terminus, C-terminus, or both termini.
Label-Free Quantitation
Quantitate differences in proteoform abundances across label-free sample types using the Proteome Discoverer™ statistical engine. Sliding window deconvolution with kDecon and Xtract unlocks robust quantitation for proteoform masses, large and small.
Antibody Identification
Search large mass data such as antibody subunits and intact antibodies using the high mass capabilities of ProSightPD. The kDecon algorithm can determine masses from large proteoforms with unresolved charge state distributions, which can narrow the search range. Integration with ProSight Annotator allows custom sequences and modifications to be annotated and searched.

Great for TD-Only Researchers
ProSightPD in Proteome Discoverer VIEWER
Get ProSightPD 4.4 in Proteome Discoverer VIEWER 3.2. Previous versions of ProSightPD (4.1 and earlier) have required a license for Proteome Discoverer in order to use ProSightPD. With the new standalone release (4.3), ProSightPD users will no longer need to purchase a separate Proteome Discoverer license, providing a more affordable option for top-down only researchers. While Proteome Discoverer VIEWER will have all the features of Proteome Discoverer BASE, bottom-up search engines SEQUEST™ HT and Mascot will not be available.
Upgrade from older ProSightPD/ProSightPC
Upgrade from older ProSightPD (4.1 or earlier) or ProSightPC licenses to standalone ProSightPD 4.4 in Proteome Discoverer VIEWER 3.2 for a reduced price. See previous option for details.
Great for TD-Flexible Researchers
ProSightPD in Proteome Discoverer BASE
Get ProSightPD 4.4 in Proteome Discoverer BASE 3.2, which includes bottom-up search engines SEQUEST™ HT and Mascot. Both Proteome Discoverer BASE and the standalone ProSightPD are available for demo.
