Peak Proteins provide intact protein and peptide mapping as a stand alone service.  All the analysis is performed on a Sciex ExionLC coupled to a Sciex X500B QTQF.  Rachel Rowlinson was recently interviewed by Sciex for their Sciex Vision Journal Issue #4.

“Proteins are valuable molecules for a broad range of applications, but their expression and purification can often require extensive engineering, analysis and troubleshooting in order to obtain a correctly folded protein with the desired therapeutic activity.  Peak Proteins provides a full service for protein manufacture and structure determination, and uses mass spectrometry as an essential part of its toolkit to deliver high quality products to its customer.”
