This high-throughput proteome profiling approach provides deeper proteome coverage with preserved biological information. The ENRICH-iST technology enables the analysis of previously undetected low- abundance proteins, facilitating the discovery of additional potential biomarkers.

Labile post-translational modifications are better preserved using ECD than conventional MS fragmentation techniques such as collision-induced dissociation (CID). Common modifications, such as glycosylation and phosphorylation, can impact the safety, efficacy, and binding activity of monoclonal antibodies but are challenging to identify. Stephen Sciuto from Agilent Technologies and colleagues analyzed tryptic digests of NIST mAb and Infliximab using an 6545XT Q-TOF mass spectrometer in ExD or CID mode. ECD provided higher sequence coverage than CID, reaching 100% for glycosylated peptides in Infliximab. The ability to pinpoint glycosylation sites using fragment ions demonstrates the power of ECD for characterizing glycopeptides.

Designed initially to expedite proteomic sample preparation, the BeatBox now emerges as a pivotal instrument for metabolomic and lipidomic sample preparation. Its highly efficient extraction of polar metabolites and non-polar lipids from tissues aids the processing of limited specimens, ideal for targeted MS approaches.

The first reported combination of microdroplet reactions with ECD fragmentation offers a quicker way to analyze monoclonal antibodies for disease treatments. Thomas Walker from Agilent Technologies and co-workers demonstrate the use of an Agilent Jet Stream electrospray ionization source to facilitate in-spray chemical reduction and protease digestion of monoclonal antibodies. Downstream fragmentation of the microdroplet reaction products with ECD provided rapid characterization of intact antibodies in minutes. Efficient ECD fragmentation yielded rich sequence information including evidence of disulfide bond connectivity and confirmation of key sequences called complementary determining regions. These results highlight this method’s potential for fast and cost-effective antibody characterization with minimal sample preparation.

ENRICH-iST effectively addresses the challenge of high diluted protein content and high dynamic abundance range, which is typical for CSF samples. By improving the detection of low-abundance proteins, ENRICH-iST is a powerful tool for advancing the discovery of new protein biomarkers in CSF proteomic studies.
