MassWiz 1.0 provides Mtb H37Rv peptide library for MS data search. Don't need it? Try a Custom database
- Tandem MS Search (MS/MS) for protein identification
Search all MS/MS spectra from a single experiment using a PKL file. Preliminary search shows the proteins based on number of matched MS/MS spectra. The selected protein's detailed page shows additonally matched peptides.
- Peptide Mass Fingerprint Search
You can search Peptide Mass Fingerprint (PMF) data using a text file containing mass and intensity.
- Peptide identification from a Single MS/MS spectrum
Search a single peptide from its MS/MS spectrum. This identification is useful for searching a peptide instead of protein. The proteins are mentioned which contain the peptide.
- MS/MS validation of candidate
If you have candidate/suspected peptides for an MS/MS spectrum, you can test its validity using MassWiz algorithm.
- Create Custom Database
for proteins of your choice
Rather than relying on complex statistics
to decrease "false positives",search in a customized
dataset which contains proteins of your choice. When you search against
proteins from a defined functional class of proteins or a taxa(e.g.
mitochondrial proteins, proteins you have sequenced in your lab, translated
proteins from DNA of an organism whose proteins are not yet available
in public databases, mammalian cell receptors etc), false positives
get decreased and thus increase confidence on results.
