Fast and Efficient Peptide Mapping of a Monoclonal Antibody (mAb): UHPLC Performance Using Superficially Porous Particles
March 25, 2014

In this work, an AdvanceBio Peptide Mapping column is used to generate a rapid and highly efficient peptide map at a traditional LC system pressure. The column achieves substantial improvements in peptide mapping during very fast run times and low system pressures, while still maintaining high peak-performance efficiency.

Peptide Mapping of Glycoprotein Erythropoietin by HILIC LC/MS and RP-LC/MS
March 25, 2014

In this application note an Agilent ZORBAX Rapid Resolution High Definition (RRHD) 300-HILIC 1.8 ?m column and an Agilent AdvanceBio Peptide Mapping column are used in combination with time of flight (TOF) mass-spectrometry (MS) for mapping EPO protein. The work demonstrates the utility of HILIC as an orthogonal and complementary approach to reversed-phase LC/MS for peptide analysis.
