PEAKS Studio 7.5

We are excited to announce the release of PEAKS Studio 7.5. There are many new features in this release that expand the capabilities for our users. Just to name a few favourites, consider:

• PEAKS PTM Profiling – to detect and quantify modifications
• Peptide Mapping - a powerful comparison tool, providing an intensity map of all the peptides associated with any particular protein.
• Peptide Feature Intensity – in one click users can analyze and quantitative peptides across all samples.
• Automated Multi-Round Search – automatically filter out high quality spectra unmatched after database searching perform additional searches against different sequence databases or change parameter settings to help explain more from your data.

These were designed to further compliment PEAKS’ proven track record of high accuracy and high sensitivity in third party studies. A complete list of improvements and additions to the software can be found here: PEAKS Studio 7.5.

ASMS 2015

The expanding popularity of PEAKS made for another exciting ASMS annual conference. During the PEAKS Meeting on Sunday, BSI gave an early glimpse into a future version of PEAKS Studio. Guest speakers also presented current research projects where PEAKS proved vital:

• Jeanne Rumsey of Washington University in St. Louis,
• Database Search Strategies for Biomarker Design in Infectious Diseases

• Dr. Cheryl Lichti, University of Texas Medical Branch,
• PEAKS and the Quest for Single Amino Acid Variants

During the conference a number of notable oral presentations and posters resonated well with attendees and emerging methods. (Please note you will need to login using your ASMS details to view the presentations.)

• Ming Yao, Bristol-Myers Squibb
• Untargeted and Rapid Detection and Characterization of Modified Monoclonal Antibodies using LC-TripleTOF and Multivariate Statistical Analysis,(Slides)

• Josh Elias, Stanford University
• Fast and Accurate Unrestricted Spectrum Interpretation: You Don’t Know What You’re Missing.

A significant list of oral presentations and posters relevant to PEAKS users are available on our ASMS 2015 webpage. Our own poster, Peptide Mapping for Quantitative Profiling of Peptide Variants using PEAKS is also available.
