Meta Protein Identification

You can get 50% more coverage, and virtually eliminate false positives just by using more than one search engine. Use inChorus to launch "PEAKS protein ID" and your other favorite search engines, then sit back, relax, and watch as all results are compiled, validated, and drawn up in one simple report. Get the right answer in one shot!

PEAKS inChorus Approach           Single Engine Approach

In other words, PEAKS not only performs de novo sequencing and identifies proteins, but compares its results with those of such MS/MS databases as Mascot, OMSSA, SEQUEST, X!Tandem and the sequence tag search tool SPIDER with no extra work or even cost to you!

The best validation of results comes not from rescoring, but simply from using two orthogonal approaches. When two search engines agree, the result is correct over 97% of the time, regardless of the score an individual engine gives. Furthermore, you can eliminate false positives and recover false negatives by comparing to de novo sequences -- this is automatic, at-a-glance information from PEAKS inChorus.

PEAKS will handle data from all major instrument manufacturers. It provides a reliable central processing tool for all instrument types.
