Protein analysis via LC/CMS with automated charge state deconvolution

The Advion deconvolution algorithm employs a combination of predictive charge envelope generation, overlap calculation with actual MS data acquired utilizing a maximum entropy goodness of fit approach followed by artifact removal through determination of peak significance. This novel approach allows for a rapid deconvolution over a wide mass range in seconds. It also allows a…

Recommendations for Transferring Peptide Mapping Methods to LC/MS Using Core-Shell Columns

With the emergence of new protein therapeutics, including biosimilars, biobetters and ADCs, peptide mapping by LC/MS is becoming more commonly used for the identification of post-translational modifications (PTMs), glycosylation, and conjugation sites, as well as primary sequence confirmation. The purpose of this study is to provide guidelines for developing optimal LC running conditions with Aeris™…
